BMW F10 8HP automatic transmission oil change
Does the F10 automatic transmission oil change also include the filter?
Yes, if you want to renew the filter. It is integrated into the oil pan, and a flush change does not clean it, so replacing the filter requires replacing the oil pan. Replacing only the pan renews just part of the oil.
How much oil does the 8HP transmission take and which oil is used?
A flush change uses about 16 litres of oil. The original oil is ZF 8HP Lifeguard Fluid, which BMW also sells. New oil is almost clear and slightly green; old oil looks darker in the container than it really is.
How is the transmission oil level checked?
The level is checked with the ISTA diagnostic tool's service function (Service Functions, transmission). The oil must be warm: for a car warmed up in the garage, about 10 minutes of idling is enough. A check done cold and with the engine off shows too little oil.
Do the transmission's learned values have to be reset during an oil change?
Opinions vary. Generally the reset is part of the oil change, and old values can cause problems, but according to some it is not necessary unless the mechatronics (the transmission control unit) is touched. You can ask a workshop about it.
