The BMW M5 is a high-performance sports sedan that is known for its powerful engine, precise handling, and luxurious interior. Like all vehicles, the M5 requires regular maintenance to keep it running at its best. One important maintenance item is the transmission fluid change.
Bmw M5 Transmission Fluid Capacity
The BMW M5’s transmission fluid capacity depends on several factors, including the specific model year and transmission type. Here’s a breakdown to help you understand:
M5 Model Years and Transmission Types:
- E39 M5 (1998-2003): This generation typically uses a 5-speed SMG (Sequential M Gearbox) transmission. Its capacity is around 7 liters (7.4 quarts).
- E60/E61 M5 (2005-2010): This generation comes with two options:
- 7-speed SMG: Capacity is similar to the E39 M5, around 7 liters (7.4 quarts).
- 7-speed Dual Clutch Transmission (DCT): BMW doesn’t specify a traditional fluid capacity for DCTs. They are considered “sealed” transmissions.
Important Considerations:
- BMW’s Stance: It’s important to note that BMW does not recommend routine transmission fluid changes for some M5 models, particularly those equipped with DCTs. Their reasoning is that the transmission fluid is “lifetime-filled.”
- Alternative Viewpoint: Many performance car enthusiasts and mechanics advise against following this recommendation entirely. High-performance driving can degrade the fluid faster, and regular service can be beneficial.
Why is Transmission Fluid Important?
Transmission fluid is a vital fluid that helps to lubricate the moving parts inside the transmission. It also helps to transfer power from the engine to the wheels. When transmission fluid is not changed regularly, it can break down and cause problems with the transmission.
What are the Signs of Bad Transmission Fluid?
There are a few signs that may indicate that your M5’s transmission fluid needs to be changed. These include:
- Slipping gears
- Jerking or shuddering when shifting gears
- Noisy transmission
- Leaking transmission fluid
- Burning smell coming from the transmission
How Often Should I Change My Transmission Fluid?
The frequency with which you should change your M5’s transmission fluid depends on a number of factors, including the type of transmission, your driving habits, and the climate in which you live. However, BMW recommends that you change the transmission fluid every 50,000 miles or 4 years, whichever comes first.
What Type of Transmission Fluid Should I Use?
The type of transmission fluid that you should use in your M5 depends on the year of your vehicle and the type of transmission. You can find the recommended transmission fluid in your M5’s owner’s manual.
