Looking for parts for your BMW automatic transmission or manual transmission? You'll find many of the parts available to service your BMW's transmission here. While internal transmission servicing and rebuilding should be done by professionals, there are a lot of things on the outside of the transmission that you can service or replace yourself. These include gearbox seals, o-rings, gaskets, automatic transmission filters, backup light switches, mounting bolts, flanges, collar nuts, screw plugs, Mechatronics, and more.

Transmission fluid is responsible for both cooling and lubricating sensitive transmission components. Over time, this fluid becomes contaminated by particulate from clutch and gear components wearing down. This contamination reduces the fluid's ability to act as a lubricant, eventually leading to increased wear and tear within the transmission. To prevent excess wear and keep your transmission in top shape, the fluid and filter should be replaced regularly. As per ZF's recommendations, we suggest performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle has been modified to produce more power than stock or if it is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination, which will help extend the life of internal transmission components, such as clutch packs and solenoids.

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.
