the getrag haves about 24,000 on it the truck has 214,000!
i haven't done any resurch on the auto to nv4500 just getrag to nv4500,just gessing that it would would be simmiler......Problly comes with some kind of adaper..........the output splines are diff between the Getrag and auto?

Kellypckp how much frame tweaking did it take. And have you driven it since you did the swap. I'd really like to try a tranny with lock-up but I'd like to hear some first hand experiances first. Thanks, Matt

od swap
i didnt have to modify the frame or crossmember at all on my 90. just drilled the crossmember holes a little farther back. i did make my trans mount though. used the same starter which should work unless one goes to the lockup trans.
