Recommended service procedure
A good way to be sure the correct amount of fluid is refilled is to measure the amount of fluid that was initially drained out. Of course this assumes the correct amount of fluid was in the transmission prior to draining.
When refilling, pump in the same amount of fluid that was initially drained out (or as much as it will take with the engine off). Then follow the procedure in the manual for checking the ATF level (run engine until ATF temp reaches 30- 50 degress C, add fluid until is spills from fill hole). Recheck fluid level after driving car and shifting through all gears.
Note
Use only transmission fluid approved for use by BMW. All other fluids will cause non-warrantable transmission damage.
Mixing different types of transmission fluids will lead to transmission failure.
