Transmission part number question

[Jerry G.]

I've been cleaning up my garage and came across a transmission I've been moving around from city to city for years. It's probably time to try and figure out what it is. I've looked through Chev by the numbers from 1965 thru 75 and cant find these numbers. Please HELP. The tail number is 3831731, the maincase is 3831704, the side cover is 3831707. The main case is stamped P 03 20. The main shaft does not have any groves. Anybody got any ideas? Thanks Jerry

63 wide ratio Muncie - should probably have a partial serial # stamp on the driver's side rear of the main case.

Re: Transmission part number question

I've looked it over and don't see any other stampings on it. does the 02 mean it was built in 1962?
