AOD problem

Skyjockey · 08-02-2005, 05:08 PM

I have a 1991 Ford E350 Van with the Navistar 7.3 litre diesel and aod tranny. Transmission shifts ok most of the time but sometimes shifts hard between first and second and second and third. But in all instances, when it shifts into OD, it wanders. It acts like it can't make up it's mind if it wants to be in OD or somewhere between third and OD. Any ideas?
Thanx in advance....

#1: check your fluid

#2: you could be losing your tranny, '91 isn't too old for the tranny to go, specially if it's been a work vehicle.
