Th475 behind a turbo 4.8 help
So I have a stock th475, it looks to have a transgo kit in it but I ordered another one just in case. My questions are as follows and please forgive my ignorance, I usually use 80es so the 3 speed life is new to me. It has the vacuum mod on the side, do I need to hook that up with a check valve inline or do I just run it straight to the intake? Also the car does not have very lofty goals, it's your basic gen 4 4.8 with a ls9 cam, pac springs and a 7665 turbo. Only shooting for around 500ish at the tire. I'm going to be using the PTC that came with it. It has a 3500 stall. Should I be looking at upgrading the clutch packs or should I leave it alone? It's going in a 83 Fairmont so it isn't necessarily a heavy car or anything. What would you guys recommend I do to keep this transmission in one piece? Any tips or tricks? Or just do the transgo kit and let it rip.
Thanks for all the help
