Recently, I had the pleasure of inviting some fellow TAT subscribers into my workshop for a ‘playday’ and the topic of battery registration came up.
For over 15 years now, European marques have strictly instructed the process to be carried out via a suitable scan tool at every battery replacement. With the procedure becoming common place in even the cheapest of modern econo-boxes, I thought it was high time to get to the bottom of what the process does, and the hotly debated question – is it necessary?
Improving on the regular old flooded cell batteries, which required regular water top up, advancements were initially made by replacing the average 6% antimony used to strengthen lead plates, with familiar sounding materials such as calcium or silver. These were first referred to as “maintenance free” batteries.
With benefits like reduced outgassing, corrosion and self-discharge, these batteries prefer a higher charge rate than traditional, around 14.4 – 14.8V, to reach full capacity.
The Achilles heel of calcium batteries is their intense dislike of deep cycle discharge, more so even than traditional flooded cells.
(Pic 1 – Ford Intelligent Battery Sensor – Mounted on the negative battery terminal, the Ford Intelligent Battery Sensor precisely measures voltage, current and temperature)
Still in the lead acid battery family, a unit enjoying rapid growth due to the harsh environment of ‘Start-Stop’ equipped vehicles is the Absorbed Glass Mat (AGM) battery – also referred to as Valve-Regulated Lead Acid (VRLA), or a lead battery with a pressure relief valve.
The earlier flooded type batteries are simply not robust enough for ‘Start-Stop’ and repeated cycling causes a sharp capacity fade after only two years of use.
With AGM technology, the sulfuric acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. Compared to flooded cell batteries, AGM has very low internal resistance, can charge 5 times faster, is capable to deliver high current on demand and offers a relatively long service life, even when deep cycled.
Unfortunately, AGM batteries are sensitive to overcharging. A burst charge of 14.4V (and higher) is OK; however, the float charge should be reduced to around 13.5V (northern state temperatures may require lower). Regular charging systems for flooded lead-acid often have a fixed float voltage setting of 14.40V; a direct replacement with an AGM unit could overcharge the battery on long drives.
AGM and other ‘sealed’ batteries (such as Gel) do not like heat and should be installed away from the engine compartment. Manufacturers recommend halting charge if the battery core reaches 49°C. High charge rates and high heat results in outgassing (overpowering the pressure relief valve) which will dry out and kill the battery.
Registration vs Programming
Although battery registration is utilised by many brands now, I will speak mainly of BMW, who have been doing it for well over a decade. There are generally two service options, Battery Registration and Battery Programming/Coding.
(Pic 2 – G Scan Battery Register – Both factory and many aftermarket scan tools have battery registration capabilities)
Every time a battery is replaced, using a suitable scan tool, the service function ‘Register battery replacement’ should be run. This completes the following operations:
Current Odometer reading is stored along with readings of previous battery replacements.
This registration function is advised when carrying out a professional battery installation, and certainly many vehicles will not clear cluster warning messages and low voltage/battery fault codes until it has been completed.
BMW Technical Training – “If the battery change is not registered, the power management will not function properly, with the result that Check Control messages may be displayed and functions limited by individual electrical consumers being switched off or having their power consumption reduced.”
I always recommend to carry out, and charge the customer for this process – however, in real world terms, my research suggests there is no evidence behind rumored alternator and electrical damage from not registering batteries. With the dynamic nature of the ‘smart charging’ systems, when fitting an identical new battery, the system is quite capable of adapting its strategy to the ‘mysterious’ new battery. Any charging adjustments based on age would be in millivolts, effecting long-term battery life negligibly.
Indeed, once a weak battery has been detected, many systems will not retract error messages/not operate some systems until battery registration is completed.
The second, and I believe most important, aspect of this topic is Battery Programming or Coding.
If a different battery has been fitted, it is imperative that the car knows the specs of this new battery to modify its entire charging algorithm.
An example –
A 2006 BMW 330i E90 model provides the following choices when programming a battery in:
Suppose our high spec model came with, and is programmed for a 90Ah AGM battery, but the customer wants to save money by fitting a 55Ah lead/calcium battery. Aside from the real capacity issues, we know that the car is going to use an AGM based charging strategy which is terrible for a lead/calcium. On the flip side, perhaps a customer is doing less driving now and an upgrade to an AGM better suited to the down time is preferable. The charge strategy needs to know this to avoid overcharging. Both situations will result in drastically reduced battery life if not programmed in properly.
Where makes like VW call for a specific code to be entered – if your physically correct aftermarket battery does not have a manufacturer recognised code printed on it, your best bet is to match up and enter a code with the same chemistry and specs as the battery you are installing – this is of course not ideal though.
(Pic 3 – Ross Tech Battery Coding – Although physically capable, many Australian sold batteries are not available for selection when coding in a new battery.)
(Pic 4– VW Battery Code – For VW, the 10 digit serial number is often preceded by the battery vendor code VA0, making the 10 digit serial number on this battery 360315F0B7.)
If a battery is staying with the same chemistry, but the Ah rating is changing, although I always recommend to reprogram the correct rating in, physically going up in Ah – ‘capacity’ – should be a non-issue. If the system wants to maintain the battery at about 80% State Of Charge (SOC), and then put energy in, the result will be that when it puts energy in, there is more capacity to put even more in. If a smaller battery was installed, the logic should still cut out based upon SOC, but the conditions may be such that it causes overcharge conditions or puts too much energy in too quick.
Many Australian batteries will not provide an Ah rating but instead a Reserve Capacity (RC). Although they are separate measurements, they are very similar in nature and there are many handy formula for calculating the Ah to be coded for your replacement battery. I find the easiest to be:
Of course having the right tool and battery for the job is always going to be best, but in a pinch (which can often happen in this wide and wonderful country of ours) the main things to remember are –
The battery being installed must be the same chemistry that is programmed into the vehicle.
Install a battery as close to the programmed Ah rating as possible – physically going up in capacity if forced.
Reference table –

Deposits formed on the plates of the battery as the electrolyte gives up its sulfuric
acid. Excessive deep cycling of a battery can cause a hardening of this deposit and make it impossible to return sulfate to the electrolyte. A sulfated battery is one which has these hardened deposits on the plates and cannot be recharged to full capacity.

The main benefit of an electric water pump comes from its
variable nature. Pulse width modulation allows the computer to
tailor fit the coolant flow to your engine’s current situation, and as
sparingly as possible. Electrification also provides several side
benefits, such as the reduced complexity of belt/chain designs
and the ability to remotely mount the pump in unused space.
Expect to see more of these modern water pumps because they
are ideal for hybrid and electric vehicles, which don’t have the
luxury of a constantly spinning mechanical engine.

Further to this, when carrying out a regular automatic Transmission Service in Browns Plains, we use a dedicated automatic transmission fluid transfer machine, ensuring the best quality service is completed.
This works like a blood transfusion for your automatic Transmission Service in Browns Plains. The machine ensures that we replace 100% of the fluid – the most critical part in gearbox longevity – unlike the drain and refill procedure others use, which often only replaces 30-40% of the fluid. Be sure to ask which method is being used by your chosen repairer when pricing your automatic Transmission Service in Browns Plains.
Transmission servicing is the absolute best way to ensure your transmission gives you trouble free motoring for the life of the vehicle.
What makes us better?
We have invested in tooling to make sure we can cater for even the highest levels of Transmission Service in Browns Plains:
We have factory level scan tool functions to complete resets and adaptations in your vehicle’s transmission control module (computer)
In an effort to keep owners from ‘tinkering’, many transmissions have complex, sometimes secretive, fill and level check procedures, our investment in data ensures only the correct fluids are used and the levels are checked by factory procedures, at the correct oil temperature (extremely important!).

As cars have evolved so has the way we service them, particularly Major Car Services.
The term Major Car Service is a throwback to when cars had more wear items, replaced quite regularly, at Major Car Services –
Moving ignition items like distributor caps, rotors and points required replacement – inductive sensors and computer controlled ignition systems now have no moving parts to replace.
Spark plugs were made of lesser materials and required regular replacement – modern spark plugs are coated in exotic metals like platinum and iridium, meaning some models can last as long as 150,000km before replacement.
External fuel filters have been replaced by complete fuel pump modules with built-in filter inside the fuel tank, which on some models are not scheduled/possible for individual replacement.
Electric vehicles do not require oil and oil filter changes.
Modern Car Servicing
The modern car is serviced differently, with much of the servicing requiring data interrogation of sensors to ensure they are reading correctly, adjustment to certain items and cleaning of others – less items are replaced, but the items are much more expensive, requiring good upkeep.
Modern servicing follows a logbook, with various components being replaced/adjusted at different times. So the 10,000km service, 20,000km service and 30,000km service may just call for a regular minor car service – with the main component of this being an oil and filter change, along with a good inspection of your fairly new vehicle.
At 40,00km, an engine air filter replacement may be scheduled on top of the regular car service. This continues with various items at different intervals.
At 90,000km on top of the regular service, the Timing Belt Kit may be scheduled for replacement, an expensive item often over $500 to complete. Does this mean this is the Major car service?
But then at 100,000km on top of the regular service, the platinum-tipped spark plugs may be scheduled for replacement – the exotic metal means the spark plugs can be fairly expensive to buy compared to their plugs of yesteryear that were replaced much more frequently.
So the question is – which of these are the Major car service? Is it based on which service costs more? If this is the case usually the timing belt service would be most expensive. However, if we are following the old-school term of Major car service, it used to mean when the spark plugs were replaced – so does this mean the 100,000km is the Major Car Service?
So when is the Major Car Service?
It is for the above reason that manufacturers no longer specify terms like Minor car service or Major Car Services – servicing is defined at different intervals, with each service being its own individual job with different items addressed based on their age and km’s traveled.
Not sure what your car is due for? Luckily, the benefit of coming to a caring independent workshop is we follow manufacturer logbook service recommendations, but with the added benefit of tailoring servicing to how you use the vehicle and giving you a heads up on items that could cause trouble in the future – rather than the cookie-cutter model of dealerships were what the book says is what you get, regardless of what the vehicle actually needs.

As an approved QLD Vehicle Inspection Station, we are able to carry out a Vehicle Safety Check and provide Vehicle Safety Certificates.
Whether you are looking to sell your car, handing it down to your children or moving to QLD from interstate, any transfer of ownership or registration change will require a Vehicle Inspection to issue a current QLD Safety Certificate, formerly called a Roadworthy Certificate.
A current Vehicle Safety Certificate is valid for 2 months or 2,000km, whichever comes first.
Electronic Vehicle Safety Certificate
As a leading approved Vehicle Inspection Station, we have fully embraced QLD Transport’s recent initiative to provide your Vehicle Safety Certificate documents electronically, rather than the older styled multiple pages handed out.
Once we have completed a Vehicle Safety Check, we can email all required documentation directly to you. Electronic Vehicle Safety Certificates have several benefits, making your life easier and saving you time. A few examples include –
An Electronic Safety Certificate allows you to transfer registration of the vehicle online. This saves you the inconvenience and queuing from a trip to the transport department, something which must be done if dealing with the older style paper safety certificate.
The moment you list a vehicle for sale, whether it be online or simply putting a ‘For Sale’ sign up (this includes vague suggestions like ‘Buy Me’ or ‘Interested?’), you must display a current QLD Vehicle Safety Certificate on the vehicle. Failure to do this will result in a large fine if caught. With an Electronic Vehicle Safety Certificate this is not required. You simply need to be able to produce your documents if asked (most commonly through email on your smartphone).
If you need a Vehicle Safety Certificate, why not call us at ourcar repair shop to book an appointment today.
We fix plenty of problems at our car repair shop in Browns Plains, and some we see more often than others. So if you are interested in how we spend our time at the Steve Sorensen Car Repair Shop – here are 7 of our most frequently seen problems.
Engine air leaks: With so many sensors on the engine monitoring air flow, pressure and temperature, any air leaks in the intake system can send things haywire – often resulting in computer fault codes indicating problems with particular sensors – with all the experience in our car repair shop we know to go for the smoke machine to test for leaks before testing sensors for faults.
Spark plugs: Another common problem we see often during a car repair service, spark plugs in the modern vehicle use exotic metals like platinum and iridium, meaning they can last over 100,000km in some models. Unfortunately this means they can go forgotten if not replaced at specified intervals, causing poor fuel economy, rough running and misfiring.
Ignition coils: Along with your spark plugs, these help to keep your engine firing on all cylinders. Ignition coils take the 12 volts supplied by your cars battery, and boost it to up to 40,000 volts to create an electrical spark at the spark plug. With such a hard life these are a common cause of misfiring. We test and replace many ignition coils a week in our car repair workshop.
Exhaust recirculation valves: These are involved in reducing your emissions and redirecting some of your exhaust fumes back into the engine to lower the combustion temperature, reducing the output of nitrogen oxide – a gas that is terrible for the environment. These valves are a ‘necessary evil’ to be able to burn petrol and diesel , whilst still passing emissions testing. Unfortunately, running sooty exhaust gas through the intake means in our car repair shop we are regularly replacing these valves, or repairing the blockages they cause in the intake
Add-ons: The main problem here is with non-professionals installing additions to their cars, such as alarm systems, radios and wireless devices. These can divert power from other areas and cause a wide range of problems.
If you have any of the problems above, why not call us at our car repair shop and ask for a quote?

At Steve Sorensen Mechanical we do lots of major car services at our workshop in Logan Qld and we always check people’s tyres during their services. So you might be surprised to learn that tyres can actually last up to 10 years, although most of our tyres need to be replaced after 6 years.
How long your tyres will actually last before they need to be replaced is another matter, because there are a number of factors involved, not least being your driving style. Whilst most people won’t change the way they drive, it helps if you check your tyres every month, not just for the usual tread depth, but also to look for cracks in the sidewalls caused by underinflating your tyres and also from the harsh Aussie sun.
Hopefully, during the early years of logbook car services, you won’t need to replace your tyres, but we have seen it happen every now and again. Here are some of our best tips for extending the life of your tyres.
Check tyre inflation monthly: On average, tyres lose 1 psi every month and the psi can increase or decrease depending on the ambient temperature. So the air in your tyres can vary quite a lot, which is why you need to check them monthly and why we also check them during your major car services.
Rotate your tyres: It’s best to rotate your tyres every 10,000km to help extend their life, but if you notice any uneven wearing on your tyres, make sure to rotate them as soon as possible. During your major car service at our workshop in Logan Qld, we can check your tyres and tell you whether you need your tyres rotated or not.
Book in for a wheel alignment: If your car isn’t driving true and tends to veer off on one side then your first port of call is a wheel alignment and you may as well have your tyres rotated at the same time.
Don’t speed: One of the causes of blow outs in trucks is that they drive at a consistently high speed for hours on end. This is particularly relevant in our hot Aussie summers when the ambient temperature is high, because if your car is overloaded and your tyres have not been well maintained – they can simply blow out.
Why not book in for a major car service or a logbook car service and we will make sure that your tyres are in good shape.

The engine cooling system has had its fair share of nips and tucks over the last few decades but the principal behind it is a simple one and stays the same – keeping the engine within a certain temperature range and providing heating for cabin occupants.
Progress in cooling systems, as with most vehicle systems these days, is being pushed by emissions and efficiency. Several tweaks to age-old components have played a part in the modern vehicle being more powerful, using less fuel and having cleaner emissions than their predecessors.
We are a long way from the days of air cooling and now seeing computer-controlled versions of well-established cooling components, including electronically assisted thermostats, pulse-width-modulated fans and electric water pumps to name a few. With these components come new fault codes and new ways to diagnose cooling systems.
Why are there wires going to the thermostat?
Electronically-assisted thermostats have been around for decades now and their operating principle is still very much the same as their earlier, mechanical ancestors. The main drawcards of electrical control over the thermostat are increased power and improved emissions.
In a perfect world the optimum combustion process in a passenger car occurs at about 110°C. With mechanical thermostats a middle ground must be struck and their rated opening temperature can open much lower than 110°C to allow a ‘buffer’ for high-load situations.
Electronically assisted thermostats have the advantage of being able to offer a much higher opening temperature. These thermostats can remain closed as high as 110°C – at this point they will open unassisted as the wax pellet melts, just the same as a regular thermostat. This creates the ideal temperature environment for emissions and efficiency.
The computer uses preset maps and watches several parameters – including engine load, vehicle and engine speed, coolant and intake air temperature – to operate the heating element and quickly open the thermostat further. This offers a rapid increase in cooling and drops the engine below 110°C. The lower temperature is ideal for making power, allowing ignition timing to be advanced closer to optimal without increasing knock. For this reason, the heating element is most often operated under high-load conditions to increase cooling.
The heating element will also be operated, even at low load, if the coolant temperature rises above 113°C to combat overheating.
The graph on this page – a simulated map that controls the thermostat heating element – shows what the computer is thinking (pic 1). The coolant temperature is lowered as vehicle load and speed increases.
Check its pulse!
From belt-driven fans to low/high staged relays, we now commonly see vehicles with pulse-width-modulated cooling fans. Pulse width modulation ticks all the efficiency and NVH (noise, vibrations, harshness) boxes for manufacturers.
The benefits of precise fan-speed control are obvious but often the speed range is not infinite. It is quite common to have preset stages of fan operation, loosely evidenced by only a handful of speeds being available when bi-directionally controlling fans through a scan tool.
Understand that engineers have worked long and hard to perfect these speed stages to provide a balance between effective cooling, energy efficiency and driver comfort. Under certain conditions a 64 per cent duty cycle may be ideal for cooling but 61 per cent may be a better option due to the noise and vibration of a particular fan assembly.
With a 10.61 per cent duty cycle (blue) commanded by the computer, this small cooling fan draws only 300 milliamps (red) (pic 2).
For testing purposes, if no scan tool bi-directional tests are available, the old theory of increasing load to get the fans on high still holds true, so set the a/c to max and turn on as many loads as possible.
With a rise in commanded duty cycle to 38.55 per cent (blue), fan current increases to 814 milliamps (red) (pic 3).
Go with the flow
The theory for going electric with water pumps seems logical – old mechanical-driven pumps, after all, rob precious power and economy.
Critical thinkers might argue that you cannot create or destroy energy, so isn’t this just putting more load on the belt-driven alternator to provide power for an electric pump? Well, there’s a little more to it than that.
Mechanical water pumps are directly linked to engine speed, so often pump more coolant than is needed. Conversely, sometimes more coolant flow would be ideal, such as during engine shut-off after hard driving.
The main benefit of an electric water pump comes from its variable nature. Pulse width modulation allows the computer to tailor fit the coolant flow to your engine’s current situation, and as sparingly as possible. Electrification also provides several side benefits, such as the reduced complexity of belt/chain designs and the ability to remotely mount the pump in unused space.
Expect to see more of these modern water pumps because they are ideal for hybrid and electric vehicles, which don’t have the luxury of a constantly spinning mechanical engine.
Where to from here?
If you think we’ve made progress in cooling systems, grab an iced tea because the future is hot. The latest semi-conductors used in hybrid and electric vehicles produce a heat flux measurement of 400W/cm², comparable to the surface of the sun!
Huge cooling requirements will be demanded from stationary vehicles and SAE J1772 electric-vehicle connector standards allow for up to 240kW of charging power.
The sensitivity of electronics creates the need for very precise and component-specific cooling and this is where glycol-coolant-based cooling systems show their age. Complex systems with handfuls of small passages become hard to bleed and regulate. The various metal components that require cooling create bi-metal corrosion issues.
We are starting to see new solutions. The BMW i3 is an electric vehicle that uses the existing a/c system to cool the battery pack through refrigerant tubes mounted in a cooling plate, which acts a heat sink.
But while the technology is changing the customer complaints will remain the same. When Mrs Jones complains that her feet are cold on morning drives, the keen technician will complement their old-school physical tests and inspection with the interrogation of data from all modules. The poorly trained will quote a pair of slippers.

At our car repair workshop in Browns Plains, we’ve found that the technology used for vehicle diagnostics has improved by leaps and bounds over the past few years. One of the big improvements is with Bluetooth technology, because now we can perform a major car service in Logan QLD, or any inspection that needs diagnostics, quickly and easily.
With the newer model vehicles having so much computerised technology, both the vehicle owner and the mechanic now have a much better tool to use for vehicle diagnostics. For example, vehicle owners can use their Bluetooth diagnostic scanner to check their vehicle’s emissions and their fuel consumption.
We often use them in our car repair workshop in Logan QLD to clear error codes during a major car service, after first identifying and fixing the problems and we can even prepare a repair report for our own records or for our customers.
Five benefits of using Bluetooth vehicle diagnostics
One size fits all: All new vehicles are required to meet specific standards for their on board diagnostics, commonly referred to as OBD II, making it much easier to identify problems across most makes of vehicles with one diagnostic tool. There was a time, not long ago, when a car repair workshop had to buy a diagnostic tool for each make of vehicle, but no longer!
Increased vehicle efficiency: These diagnostic tools allow for precise control over your vehicle’s fuel and ignition, making it fairly easy to increase your vehicle’s efficiency and reduce your carbon footprint.
Reduces repairs: This tool helps your mechanic to pick up problems that you might not have previously noticed, saving you serious money down the track on expensive repairs. Vehicle owners can also use the diagnostic tool at home, reducing the number of trips to the mechanic or booking in their vehicle for a timely major car service in Logan Qld, before the problem exacerbates.
Faster vehicle diagnostics: All the mechanic needs to do is identify the codes shown on the diagnostic tool and it will quickly reveal the source of the problem. This saves you hours of time, because for many issues, the mechanic no longer has to peer into the depths of the engine, trying to locate the cause of the problem.
Cheaper bills: When your mechanic can perform your major car service or repairs much quicker than before, your costs may go down, and everyone’s happy.
Don’t forget to book your vehicle in for a major car service in Logan Qld at our Browns Plains car repair workshop. We can even demonstrate some of our technology to you, so you know you’re in good hands.

As is now common knowledge, modern diesels build up restrictive carbon in the intake manifold which robs power and economy.
Even the most powerful of on car cleaners cannot break down large buildup safely and through our research and development, we believe the best bang for your buck, and most professional job is achieved by off-car ultrasonic intake manifold cleaning.
What to do about it?
We recently invested in an ultrasonic cleaning bath to ensure that when items do need to be removed from the engine, particularly intake manifolds, we get a perfectly clean result to ensure the labour spent on removal is worth it.
Take a look at the results we got cleaning a choked up Mitsubishi Pajero 4M41 diesel engine intake system this week, including the upper and lower intake manifold and EGR (exhaust gas recirculation) valve – the results speak for themselves.
For all your diesel diagnostic issues, ranging from check engine light, poor fuel economy, blowing black and white smoke, hard starting and rough running.

As many manufacturers share the same brand diesel injection systems from companies such as Denso, Bosch, Pierburg and Siemens, we specialise in many diesel vehicles including:

What are your thoughts on the manufacturers extending service intervals?
I believe, like so many other things in the business of making cars, extended service intervals have primarily been introduced as a marketing tool to sell more cars. We know the tolerances are smaller, the components more expensive, the emissions ever tightening â the service schedules simply do not reflect this, even taking into account the impressive advancements in lubricants.
Online tools can easily calculate servicing costs of a modern vehicle, and savvy buyers include this into their decision when choosing a vehicle. If I compare two similar cars but one makes me suffer the inconvenience of the dreaded service twice a year rather than once, one has a distinct advantage.
Digging deeper than a car buyer’s weekend research, the dealer’s story starts to unravel:
Filled for ‘life’, is this the expected life of the component, the life of the vehicle or the life of the warranty?
Some schedules appear to be written by the marketing department rather than engineers, how can a Jeep and a Mazda sharing the same engine recommend such blatantly different service schedules on a whole range of things from engine oil to filters? Often the big ticket items will conveniently require servicing just as the car finishes its capped price servicing period.
How can a car built in January have a distinctly different service schedule from an identical model built in February?
Ridiculous oddities like a manual transmission car having an external fuel filter but the automatic variant using a no replacement specified in-tank filter.
What issues have you seen due to extended service intervals?
Of course oil sludging is the main culprit, without good advice most customers don’t understand that 15,000km of primarily long distance driving is worlds away from 15,000km of stop start short distance city driving.
Customers start to treat the car as an appliance rather than the sophisticated machine it is. If the oil can go 15,000km, surely you still don’t need to check the tyre pressures right?
Rather than regular low cost maintenance, service items are becoming ludicrously expensive and without good records it’s difficult to know if that new customer who just drived in has had their $350 in-tank fuel filter replaced at the scheduled time. Has their transmission ever had its $300 synthetic oil change with no fluid level check procedure available? We will just have to wait until it has problems, requiring expensive diagnosis and repair.
What used to be a reasonable expense for regular filter replacements can quickly turn into components further down the line needing replacing â by the time the water in diesel light is on, every further kilometer can be $100.

A car transmission service is an important part of maintaining your vehicle and should be performed every year if possible. This is because the normal wear and tear on your transmission creates millions of tiny abrasive metal particles that fall into your transmission oil and can cause your transmission to fail, if your oil isn’t changed very often.
It doesn’t matter whether you have an automatic or manual transmission, a car transmission service is still an important part of keeping your car healthy and safe on the road. This type of service won’t take very long and includes the following:
Draining out the old transmission fluid, and removing and cleaning the pan.
A thorough inspection of the drained oil for any indications that there are hidden problems in your transmission.
Removal and replacement of the transmission filter.
The pan is replaced and a new gasket fitted.
Your transmission is filled with new, clean oil and tested for leaks.
We road test your car to make sure that it is operational, after your car transmission service in Browns Plains has been completed.
As you can see, this is a very simple and quick service, but it is one that is often forgotten or ignored by many car owners. If we find during the service that there are a lot of fine metal filings in the oil or that the fluid looks to be contaminated, then we will recommend a transmission flush, as well as a service.
This flush helps to remove any trapped contaminants or metal filings that were not flushed out when the oil was initially drained during the car transmission service. A flush is not always necessary, but it is more likely to be needed if you haven’t had a transmission service for a few years. This is because the new, clean oil is likely to loosen this trapped debris, which then washes around your transmission and often results in huge and costly repair bills.
At Steve Sorensen Mechanical, we offer a fast and efficient Transmission Service in Browns Plains to our clients and we guarantee all of our work. So call us on 3809 2711 and book your car transmission service today.

Owning a car can be an expensive undertaking and having to book into a car repair workshop for every service or problem that occurs, can seriously add up the dollars over the life of your car. So how do you know when it’s OK to tackle problems yourself and when it is much better to look for a qualified mechanic?
To help you out, here are 3 scenarios when it will serve you well to call your local car repair workshop, rather than attempt to troubleshoot or fix problems yourself.
When you don’t have the knowledge or experience
If you struggle to do your own services or you have no idea how to replace an alternator, replace a brake cable or change the spark plugs, it is best if you leave it to the experts. Of course, you can educate yourself and become quite a handy home mechanic, but unless you are passionate about learning DIY mechanics, maybe it’s best if you call your local car repair workshop.
When you don’t have the right tools for the job
You might have a fair amount of knowledge and even know what needs to be done to fix your car’s problems, but if you don’t have the right tools then you will be even more out of pocket. Some speciality tools can cost a fortune, so unless you want to go into business as a mechanic, why spend all of this money when your local car repair workshop already has these tools!
When you don’t have the time yourself
Sometimes having the knowledge and even some of the right tools isn’t enough, because who has the time to spend working on their cars every weekend? Unless rebuilding cars and keeping them in pristine condition floats your boat, then your local mechanic can save you a lot of time and angst by doing all of your services and repairs on their time. This leaves you free to enjoy your weekends with your family, instead of working on the car.
If you want to free up your weekends and leave all of the hard, dirty work to someone else, call us at Steve Sorensen’s Mechanical car repair workshop in Browns Plains and we will have your car up and running in no time at all.
