BMW E90/E92 M3: Changing Manual
Transmission Fluid
The M3 manual
transmission has a cooler that requires the BMW computer to cycle on/off to
completely extract old fluid and take in new fluid. I plan to change it often
enough that I can change it just like any other BMW 6 speed and not worry about
the small amount of residual fluid in the cooler/pump and will be able to
exclude the step I cannot perform with the computer. There is also a screen
type fluid filter at the pump I plan to check every other change and clean or
replace. The potential consumables that might need to be replaced for this
fluid change are below, if checking the oil screen filter the gasket ring (part
13 in right diagram below) requires replacement according to TIS:
