On an '89 750iL, I have been advised not the change the transmission fluid. The car has 130,000 miles and I have no idea when the fluid was ever changed. I have had it for about 12,000 miles. A mechanics ahs suggested that changing might cause more problems because it may have never been done. Any ideas? You can definitely feel the torque converter lock up but can't feel the other gears.
BYW, the board is the reason why my Bimmer is still running today. Thanks
