Had my Diesel 48RE tranny rebuilt by CRT in Indiana. Converter kept going into lockup at stop lites, so here is what I found when I dropped pan and took filter off. Look closely, there are a couple of issues. He also sent me a V-10 47RE converter the first go around and then a diesel 47RE the second time. Finally bought a 48RE locally cause this had drug out for months and I needed truck. Guess how much help he was when it was all said and done. He offered to pay me for the first wrong converter when I sent him the second one back, and this was after he had told me he would take care of swapping converters. I told him if he wouldn’t honor his word, to stick it up his a$$.
