BMW transmission fluid is stated to be 'lifetime' with no maintenance necessary. That being said, if your BMW has over 100,000 miles, it is time for a filter and fluid change. Keeping this fluid and filter serviced is absolutely imperative to ensuring a long service life. Turner Motorsport carries only BMW approved fluids that will have you shifting smoothly for years to come.

BMW's xDrive all-wheel-drive system relies on transfer case fluid to lubricate its internal gears and bearings, much like a differential. This fluid helps reduce friction and prevent premature wear from metal-on-metal contact. To maintain optimal performance and extend the lifespan of your transfer case, we recommend draining and refilling the fluid approximately every 60,000 miles.

Used by BMW for limited slip differentials. Rear differential fluid, also known as differential oil, is a lubricant specifically designed for the differential of a vehicle. The differential is a crucial component in the drivetrain that allows the wheels to rotate at different speeds, particularly when the vehicle is turning. The fluid helps in several ways: Lubrication: It reduces friction between the moving parts within the differential, such as gears and bearings. Cooling: It helps to dissipate heat generated from the friction and the operation of the differential. Protection: It prevents wear and tear of the gears and bearings, extending the lifespan of the differential. Performance: It ensures smooth and efficient operation of the differential, contributing to overall vehicle performance and handling. The fluid needs to be changed periodically as part of regular vehicle maintenance to ensure optimal performance and to prevent potential damage to the differential components.

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.
