BMW Transmission Filter Kits & Transmission Service Parts for BMW F85 X5 M S63 4.4L

Clear BMW chassis

Please ensure your correct model is selected

BMW automatic transmissions require a regular filter and fluid change. While BMW has recently implemented 'Lifetime' fluid on most current models, we feel that it is critical to change the transmission filter and flush the fluid at least every 50,000 miles. We carry the BMW transmission filters and special transmission fluids for your BMW.

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 complete kit includes bearings, clutch packs, shims, magnets, retainers, hardware, seals, and other necessary internal components. Until now, the only solution to repair these failure-prone transfer cases was to replace them with a complete assembly at the dealer or install a used assembly at the local shop. No other options were available due to no offering for internal components. All the components offered in Rein's Transfer Case Overhaul Kit are OE, identical to the original parts on the vehicle direct from the factory. Features: Includes all OE components Solution for T-cases that were damaged from overheating or lack of service made to strict OE engineering quality standards 4 year/50,000 mile warranty The kit was designed to service the ATC 45L transfer cases found in the F85 & F86 models as BMW part numbers 27107854164 and 27105A371E4
