BMW Drivetrain Parts for BMW 8 Series E31 (1991-1997)

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.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This kit includes Redline D4 ATF, the transmission filter, gasket and bolts.

Kit Includes:

  • Automatic transmission filter with associated hardware
  • Oil pan gasket
  • Drain plug with sealing washer
  • Fill plug with sealing washer
  • 6 quarts Redline D4 automatic transmission fluid

Fits the following BMWs:
E31 BMW 840Ci (from 09/1996)
E39 BMW 540i (from 01/1997)
E38 BMW 740i/iL (from 01/1997)
