Help ID Muncie M21
I have a 1970 (P0R29B) M21 Muncie 4-speed transmission. The main case number is 3925661 and it does not have a VIN stamp but has what looks like TO followed by 38837 near the date stamp (the 38837 is in very small/fine characters). There is a steel tag on the driver's side that reads 545767. I was told it was bought at a Pontiac dealer parts counter in 1970. I cannot find anything on the tag number and I don't know how "replacement" transmissions were marked.
Any help? |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
