Rein BMW Transmission Filter Kits & Transmission Service Parts for BMW Z Series E85/6 (2003-2008)

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.

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.

Rein OE Quality Automatic Transmission Service kits address the short-lived valve body sealing sleeves and adapter in the ZF 6HP transmissions. This kit includes the necessary direct-fitting sealing hardware to conveniently service the shrunken valve body sealing sleeves during the recommended fluid and filter change interval of 62,000 miles / 8 years at the latest. The ZF 6HP19Z series transmission is a very durable and powerful unit that can last for many miles if serviced in time to allow the valve body to maintain proper fluid pressure. The slightest drop in valve body fluid pressure in this unit leads to premature transmission bushing and or clutch wear, along with contamination and overheating of the fluid. Rein recommends the OE or Pentosin ATF-1 synthetic automatic transmission fluid for this job.
