BMW Drivetrain Parts for BMW E90 M3 S65 4.0L

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

BMW claims their transmission fluid to be a "lifetime" fluid, however is recommended to be changed every 60,000 miles to ensure a longer transmission life. Though not exposed to the same level of heat and contamination as engine oil, transmission oil still breaks down over time due to heat and becomes contaminated as your transmission wears. Old contaminated oil can lead to excessive wear and tear on sensitive transmission components which could lead to slow shifting, slips, and even complete failure. This is also true for the transmission filter. The filter removes metal particles from the transmission fluid and eventually begins to clog, preventing fluid from passing through the filter easily. This leads to excessive wear and a reduced transmission lifespan if not changed. Not sure if this kit is right for your BMW? Contact our sales staff with your VIN to confirm the exact part you need.
