Hi all, I have a 4 speed in my 42 3/4 ton Chev. It leaks so I'm wanting to redo it with new bearings and seals. Does anyone know where I might get parts. Everywhere I've checked carries parts for the 3 speeds but not the 4 speed. The tranny is still in the truck and I use it to get to work. There was water in the trans when I bought the truck, very little pitting showed on the surfaces of the teeth. She's noisy in all but 4th and reverse.
