Hey everyone. I'm looking for help deciphering the code on my 700r4. The code is 1BBM216C. I know that it is a def a "91" and a 30 spline, but what I'm curious about is what vehicle it came out of. I've looked everywhere online and cannot come up with an answer. I'd appreciate your help. Thanks.
1BBM should come back to GM 08686953 - Replaces 8671990, 8683962. 91-92 Caprice, Road Master, and Custom Cruiser.
