Genuine BMW BMW Transmission Filter Kits & Transmission Service Parts for BMW 3 Series G20 (2019+)

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.

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.

Servicing your rear differential at regular intervals is important to ensure you maintain both performance and a long lifespan. Over time, the differential fluid can break down, lose its lubricating properties, and become contaminated with metal shavings and debris. Regularly replacing the fluid ensures that the gears and limited slip differential clutch packs are adequately lubricated, reducing wear and tear. Regular maintenance also helps identify potential issues before they become major problems.

This kit includes Genuine BMW differential fluid designed specifically for your M Sport differential and a brand new fill plug. The factory plugs include a rubberized seal that compresses over time and may not seal properly when reused.

One unique aspect of performing this service is the removal of the lower differential temperature sensor. Unlike many typical BMW differentials, this differential does not use a traditional drain plug and instead uses the temperature sensor as a drain plug. This sensor is removed to drain the differential fluid and is replaced before refilling. If you'd like to replace this sensor as well (not included in this kit), please see our recommended items or search BMW part number 33107847469.

NOTE: This kit includes 3 500ml bottles of diff fluid. BMW claims that only 1 Liter of fluid is necessary, but we found that 2 500ml bottles were insufficient. The third bottle included also allows for a minor flush of the old differential fluid before refilling.

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. This item fits the following BMWs: E71,E89 Z4,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4,F30,F31,F32,F33,F34,F36

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: Automatic transmission filter Oil Pan Gasket & Installation Hardware Drain plug with sealing washer Fill plug with sealing washer 7 Liters of Genuine BMW ATF 3+ Fluid 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.
