Greetings, I am new to the list. I have a couple issues with my 1997 540i that I think are tranny related. Here are descriptions:
While going down a smooth road at constant speed the car lurches ever so slightly. I can see the tach change rpm slightly and at first thought it to be electrical, but now think more tranny related.
Same smooth road going at constant speed all of a sudden it sounds like a ran over some ridges in the road and I can feel the vibration to match. Weird.
Any ideas?
