I've got a 1996 XJ with an AW4 that has a very weak reverse gear. I mean it's so weak the previous owner didn't think it worked at all, it will move the Jeep on a flat smooth ground but if it gets any resistance it will stop no matter how much gas you give it.
With the TCU unplugged first, third, and fourth work just fine, reverse is weak with the TCU plugged in or unplugged (as you would expect).
Now I don't have a lot of automatic transmission experience but by looking at the book I'm thinking it might be a physical blockage in the manual shift valve in the transmission? It can't be a first/reverse clutch issue because first has the right pull.
So what do you think? Has anybody seen this issue before, if so what did you do to repair it?
The transmission only has 120k on it but there was an unsmart previous owner involved...
Thanks
