real challenge fail safe desperate !!

I know your issue sounds far more complicated but I've had transfailsafe come on just because my MAF was either disconnected or I had the vacuum tube to the throttle body disconnected, causing a massive vacuum leak.

I'm assuming the speed sensor on the transmission has been reconnected?

I have many problems with my transmission. Was wondering if I could get some help? I have a 2001 X5 4.4i .Sorry, I didn't mean to jump in on your thread, but I can't seem to do it any other place.

49: Symptom gear check
52: Gear check 2
59: Stalling speed
54: Gear check 4
50: Gear check 1

OBD2 codes are:
PO20
PO31
PO32

Thanks guys.

Wayne, you are saying that the trans failsafe mode came on because of the MAF being disconnected? what other symptoms did you have?
