ALUMINUM a833 OVERDRIVE TRANSMISSION

I'm selling this transmission for a friend. A-body & F-body aluminum 4 speed overdrive transmission I have no idea about how many miles are on it but it spins free and smooth I didn't see any broken or chipped teeth it did shift in and out of all the gears freely.
These transmissions work great with a slant 6 or small V8. $350.00 plus the ride. The side cover will need to be sealed it was removed when I got it and I took it back off for the pictures.
PM me with any questions Thanks Bob
