It was rebuilt. Therefore there shouldn't have been any reason for it to go bad. Yes R still wasn't working. Hopefully it's poor oil pressure that caused it not to go into gear. The car wasn't driven a ton after the rebuild. I'm gonna do a solenoid check soon as I get my multimeter back from a friend.

It was rebuilt, yes, but not correctly if reverse wasn't working. And having a catastrophic failure in such few miles since the rebuild also points to a bad or incomplete rebuild. Perhaps you accidentally overlooked a cracked or damaged part.

True enough, but I know that the rebuild was done step by step according to the ZF mani. It was the first full auto tranny rebuild either of us has done. While I have been around a lot of them at the shop, I've never actually handled one myself yet. With that said, with reverse not working, we came to the conclusion that one of the pressure lines may have slipped or fallen off of the bottom.

Regardless, 2nd times a charm man. We will get it figured out. :)

So found out the issue.

got the trans taken apart and it was indeed the Trans pump gear. the splines just shreaded off. I contacted Transtar and a couple other places but i'm not having any luck in finding the gear, and a rear bearing.

Any help at where to source these would be great.
