I have looked into rebuilding the transmission and found that it is very costly. My buddy has a spare transmission for his old truck which was a 4wd and a 1993 1/2 ton. my question is will this tranny work for my truck or is it a different tranny becuse its a 4wd.
Hi, yes they are different the tail houseing is different it's made for the transfer case to bolt up and your isn't ,unless you find a tranny man to make the changes on it, it won't work , good luck Slim
