BMW Drivetrain Parts for BMW E90 M3 S65 4.0L

Clear BMW chassis

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.

The DCT transmission in your BMW is nothing short of incredible and exhilarating, but also astronomically expensive to replace. BMW has been labeling fluids as "lifetime" for quite some time now, and as enthusiasts and owners have learned over the years, there simply is no fluid that last a lifetime. With that being said, Turner Motorsport has assembled a proper DCT service kit that takes the guesswork out of the equation. No need to track down the correct fluid and plugs, simply open the box, and get the job done the correct way. By servicing your DCT transmission, you will be assured that old, broken down fluid won't cause a several thousand dollar nightmare. Turner Motorsport recommends this service every 40,000 miles to keep your transmission going strong for years to come. Kit includes: 5 quarts of Pentosin DCTF-1 fluid DCT transmission cartridge and suction filters Drain and fill plugs Oil pan with gasket

Kit includes: 5 quarts of Pentosin DCTF-1 fluid DCT transmission cartridge and suction filters Drain and fill plugs Please note: We include 5 quarts of DCT fluid because without a GT1 diagnostic tool and much more involved labor, you will not be able to replace over 5 quarts of fluid. Many elect to do this service and simply flush the fluid 5,000 miles later to ensure all fluid has been flushed, but this is not mandatory.

Wheel bearings on modern vehicles usually need pressed in. If that is the case with your vehicle, specialized tools such as a shop press may be needed to install this bearing. Check what is required to do your wheel bearing prior to ordering. Wheel bearings can need replaced for a number of different reasons. On some vehicles, when removing the front axles, it is required that you also replace the wheel bearings before reinstallation. If the wheel turns with a gritty feel or there is a loud metal to metal noise when on the road, your bearings have failed.
