I have my transmission serviced (fluid changed, filter replaced) every 30,000 miles.

Our transmissions come from the factory with what BMW calls a "lifetime" fluid, but many of us on this board believe that no fluid is truly a "lifetime" fluid.

BMW, Mobil1, Red Line or Royal Purple all make appropriate fliuds. Depends on what you want to spend

Do you have auto tranny? If so how many bottle do you use to fill it back up? I want to do mine but only say DIY on manual tranny.
