MM7 4 Speed overdrive transmission

Does anyone know where to find a Chevy MM7 manual transmission? That is the 4 wheel drive version cast iron case. The 2 wheel drive aluminum case version is the MY6. They came in Chevy trucks from 81-88 I think. It is really a Mopar A-833 transmission with a Chevy bellhousing.

Re: MM7 4 Speed overdrive transmission

More importantly the MY6 MM7 had a GM input shaft and GM splines on the output end.
They are indeed an A833 with some oddities.
If you find one make sure you get the shifter and all three linkage arms & linkage rods.
They're fairly rare.
