I have a 1990 3/4 ton 4x4 with the cummins and the tranny kept slipping out of 5th gear. So my buddy and I pulled it out the other day and took it down to this guy that would rebuild it for me. He called me and told me that it was going to be $2200.00 dollars. I was floored, he said it needed a main shaft and 5th gear sinkrow. I am woundering if there is a place or places I can go to get parts or a rebuilt tranny. Thanks for the help Lance!!!

Some interesting reading as well as parts for the rebuild.
