I just bought a 1980 TA with a 455... I have no idea what the tranny is, I haven't looked yet. But, it slips in every gear and is really pissing me off. I read about the TH200-4R in GM High-Tech performance magazine, and was wondering if that would be a good way to go. I hear it's a tough little tranny, but also has overdrive. I'm in the Army and do a lot of highway driving, and this car is going to be driven regularly once I get it up to snuff (have to rebuild the 455 too).

So anyway, do you think this is a good idea? Can this tranny work on a 455? What about the 4th gear, I'm supposing I'll have to get a special shifter. I'm mechanically inclined, but this is my 2nd engine rebuild and this is my first project like this by myself. Any tips?

By the way, you're right about the 301's, I spun a bearing in mine ('79 formula) and traded in a 400 I rebuilt... and it was wonderful!

Thanks a lot

Mike
