Trans is on the way out. Any companies out there that sell them off the shelf built and ready to drop in? I have a 2000 SSEI parts car with a rebuilt trans. Any idea if it is a direct drop in?
It should be a T65E. It's the same gearbox as the 3800 powered Grand Prix, NA and supercharged. The T85E from the Northstar powered Cadillacs can also be made to fit, but it's a project.
Google or call your local parts store or start hitting up scrapyards.
