Looking for some advice please. I have a 1977 Y82 Trans Am with the Pontiac 400 & automatic tranny (does NOT have the W72). I plan on doing a frame off restore once I get everything figured out what I want & who I want to send it to (RMC, Texas Trans Am, Florida Trans Am, etc. Any advice there also). I want to build up the engine to around 400 hp which I read is pretty easy to doÖ so my question is, what is a good replacement for the stock tranny? Should I rebuild it, is there a better aftermarket replacement? I called Tremec but they donít make any automatics. I thinking I want overdrive for long trips but definitely need it beefier for the higher hp. Thanks guys. Btw I did a search in the forums from years ago & found out about a 200R4 but looking for any more new info.
