Tranny Id needed.

According to the serial number and the other numbers stamped in the pad it's a 1972 model year regular 4 speed A-833 tranny.
And the car was assembled in Hamtramck. Michigan.
The majority of the V.I.N. for the car it came out of is on the pad : 2B219425 are the last numbers for the car it was installed in.
PP833 means that it's a regular 833 transmission, and 3764 is a date code which is the 10,000 day calendar.
Finally, 0028 is the number of the transmission built that day, which means it's the 28th one built that day.
I hope this helps...
