Does it have a low first gear?

If so, its an SM465, and there are parts for it all over the net. If its got overdrive, or doesn't have a regular low gear, then it is something else.

Can you possibly get pictures of it? It might be a car transmission that was swapped in

Re: 1984 4 speed manual

You may have the 4 speed overdrive trans that was used in the early to mid 80's. The GM production code is MY6, and the transmission is a New Process A833. A dealer can check your VIN number and tell you if that's what you have.

You should be able to get parts from the dealer or through a transmission shop. I've purchased seal and gasket sets through trans shops at reasonable prices. The shifters used on this trans were made by Hurst.
