Low fluid levels: Though it may help to do a transmission fluid exchange if your transmission fluid dips below a safe level, it's really time for a transmission inspection since you shouldn't be losing fluid. What are symptoms of bad drive shaft versus problem with the transmission? My 2002 BMW X5 seems to "stutter" while accelerating in higher speeds (like accelerating into 3rd gear). Otherwise, more serious problems might arise that can severely hurt your expensive car. I was asked to do a write up on my transmission experience with my E60 550i. Low fluid indicates a possible fluid leak. Transmission whine FIXED!!!!! As Kirt Koeller suggested, the problem was indeed caused by an aftermarket filter and a bad "O" ring. - Nick at Pelican Parts.
