Transmission fluid helps to keep the metal components within the transmission adequately lubricated and cooled. This allows for the components to shift against each other with ease during gear changes. As a result, your vehicle’s transmission should function smoothly and efficiently, to maximise power transfer and the longevity of your transmission.
In many BMW vehicles, you will discover the presence of a special transmission fluid featuring ‘lifetime oil’, which is said to eradicate the need to replace your transmission fluid for the entirety of your BMW’s life. Unfortunately, this is certainly not the case. The transmission oil starts to break down from the moment it drives out of the dealership, whilst it does last longer than some transmission oils, the BMW transmission oil still degrades like any other oil.
In this article, we will be discussing the degradation of BMW lifetime oil in transmission fluid, what you can do to spot the symptoms, and how you can ultimately resolve the problem.
What is ‘Lifetime Oil’ Transmission Fluid?
The ‘Lifetime Oil’ transmission fluid was developed to be a superior alternative to conventional transmission fluids which were available in most ordinary cars. Indeed, this type of transmission fluid has been shown to last for a much lengthier period of time in BMW cars. However, it does not completely eliminate the need to give your transmission system attention at all. Contrary to the name, lifetime transmission fluids are not designed to last for the entirety of the vehicle’s life. After driving about 100,000kms, you will want to keep a close eye on your transmission fluid, and arrange to have it changed by a professional should you notice any problems start to occur.
What are the Signs of a Degrading Transmission Fluid?
100,000kms is quite a fair distance for a vehicle to travel; so, if you’ve bought your BMW brand new off the market, chances are you won’t have to worry about your transmission fluid for more than a couple of years. If you’ve bought your vehicle second hand however, then you may want to be a bit more vigilant when looking out for the signs of degrading transmission fluid especially if the vehicle has been used in towing applications as that will accelerate the transmission wear.
Degrading transmission fluid can result in the following symptoms:
- Transmission fluid with a dark, burnt colour (darkens further with age)
- Delayed gear shifting
- Difficult time changing gears
- Vehicle hesitant to change gears
- Transmission slipping (changing gears only to have it slip back into another gear)
- Overheating of the transmission (you may smell burning coming from the transmission or notice smoke)
If you notice any of these symptoms occurring, then it is crucial that you arrange a transmission service with your local service provider.
How Can I Replace my Vehicle’s Transmission Fluid?
When you’re in need of a transmission fluid replacement, also known as a ‘transmission service’, then it’s best to consult experts and turn to a BMW mechanic who can provide your vehicle with the proper care and maintenance it requires. A transmission service focuses on replacing all of the old fluid with brand new fluid, and replacing the filter and relevant gaskets whilst a simple transmission fluid change is used to drain out solely the dirty fluid.
When you turn to a mechanic, they will have the relevant tools, knowledge, and expertise necessary to determine exactly what your BMW vehicle needs. They will be able to provide your automobile with quick and efficient services. Furthermore, they will be able to answer any questions or queries you may have about the process, whilst providing you with helpful tips on how you can ensure the health and smooth functioning of your BMW vehicle. As such, we’d always recommend turning to an expert for such a service.
