Has anyone done this before? I've looked underneath the car and it has a drain plug but no fill plug / dipstick. TIS recommends to fill the transmisson where the drain plug is. Unless the tool is special, how can you take out the filler tube without trans fluid coming out also? I have the auto trans filter ordered.



I read some post over on bimmerforums - and some of the dudes are saying that they remove the transmission and tip it upside down to replace the trans fluid.
