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.

These include gearbox seals, o-rings, gaskets, automatic transmission filters, backup light switches, mounting bolts, flanges, collar nuts, screw plugs, Mechatronics, and more.

Transmission oil pan with integrated fluid filter. Found in all variants of GA8HP 8 speed automatic transmission. 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.

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Kit Includes: OEM Hengst Automatic transmission filter OEM Hengst Oil Pan Gasket & Installation Hardware OEM Hengst Drain plug with sealing washer OEM Hengst Fill plug with sealing washer 7 Liters of Liqui-Moly Top Tec 1800 ATF NOTE: Depending on the model, an additional liter of fluid may be necessary if you are draining your oil cooler or removing the valve body. As per ZF's recommendations, Turner Motorsport suggests performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle is modified and makes more power than stock or if your vehicle 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 like clutch packs and solenoids.

Interval transmission fluid changes are often recommended for manual transmissions to ensure long-term reliability and maximum wear prevention. Fresh fluid will prevent small amounts of metallic build up from preventing fluid flow and clogging filters and narrow channels.
