Auto Transmission Filter, BMW - E82 128i, E9X 325i/328i, X3 3.0si (GM GA6L45R)

This is a full service kit for the GM 6-speed automatic transmission used in 2007-2010 E82 128i, E9X 328i, and X3 3.0si models. Automatic transmissions use "lifetime" fluid but the transmission can be serviced with new fluid and filter*. This service kit includes only the filter. Other kits may be available that includes more parts - see our Related Items list below.

* - Note that changing the fluid on automatic transmissions can be a very technical process that requires a precise procedure, special tools, and/or professional-level diagnostics software. There is no doubt that fresh fluid will perform better than used and dirty fluid. However, most of the problems we hear come from an improper transmission flush where particles and debris block fluid flow or a failure to set the correct fluid level after. We believe automatic transmission fluid service should be left to a professional BMW technician and that extended fluid service (>50,000 miles) is acceptable as long as the fluid level is regularly checked and maintained.
