Hello all I'm Chris.....I have a 1987 Pontiac Grand Prix. It has the 3.8L V6. What tranny did they put in these? It's a 3 spd I do know. The reverse doesn't engage soo I'm looking to replace. Is there any swaps that wouldn't be a huge custom job? Thanks I'm glad I found this board!

87grandprix,
Welcome to the site! Just a guess on the transmission, maybe a Turbo Hydra-matic 200C?

Welcome,and yes,your trans could be a 200,but a th350 could swap or you could do a rebuild on your trans. I believe you would need the B.O.P trans for the swap though. B.O.P meaning Buick Olds Pontiac..

some came with a TH350C. look at your trans if the tail shaft housing bolts on it a 350 if the case is 1 piece it a a metric 200. some of the 200's say metric on the bottom of the pan as well.
