I just bought a used AOD trans and installed it, the guy said it worked fine when he pulled it to swap to a T-5 trans, it works fine in reverse and shifts from 1st to 2nd with no problems, but it won't shift up into 3rd or OD, just gets to a point where it should shift and quits pulling. Is there anything I should check with it still in the car or just drop it and rebuild? The bushing on the TV cable is fine, the cable is working properly and the pressure is good. I had wanted to use it while rebuilding the trans I took out because it has upgraded parts in it but was having issues with reverse.
