I happy with all the feedback lol. So thanks everyone for all the suggestions, I think ill be contacting one of the transmission builders on here as to what parts I'm going to need. Ohh, another question, i make some of my cash for building this car by buying other cars and fixing them up to sell. The current project is an 04 Grand Prix GT, i bought it from the previous owner with a damaged fender, passenger door, and broken mirror. I bought a new door and fender and had my body man repair a few dents and repaint the parts so it looks pretty good now. The last problem i have with it yet again is the transmission. Theres a shudder when it shifts from 1st to 2nd and i can't quite figure out what it might be. I dunno if the clutch packs are starting to slip or if the tranny just needs to be flushed. Nothing would surprise me, the last owner took real sh*#@y care of the car, took me 2 hours to get all the crap off the interior.
