Hi, I have this unsolved discussion with my mechanics and i really don't know what to do...Please give me some hints
I have a '92 E36 325i 24v automatik, and need to change the gearbox oil and the gearbox oil filter. As I understood, this kind of gearboxes swallows 9 liters of oil, but you can't change it all only if you take it off from the car!!!
Otherwise, if you dismount the outflow screw, you'll drain only 3 liters from it. I don't know what to do, is it necessary to change all the 9 liters and dismount the gearbox from the car? Cause I really don't like this kind of operations...
And about the oil...I couldn't find anywhere some specs of oils i can use...it only says "BMW original"...Please help! Thanks in advance.
