I have a 94 12 valve and when you gas it it holds the gear and will not shift until you get out of it. It has an auto tranny. Can someone help me with the shifting problem?I would like to know how to fix my problem.

i kind of had the same problem your describing, it turned out to be the throttle position sensor (TPS) i just had my shop throw on a new and fixed the problem, but from what i hear you may be able to adjust it, but not 100%sure if that'll work im sure some more people will chime on...good luck

Mine has a similar problem. Mine will shift fine , but the 3-4 shift, the truck will be losing power. Then all of a sudden, it will shift into OD. Lost a couple of races because of that!!!
