My car is getting a rebuilt trans today. All new internals. I had the option to get upgrade clutch, upgraded stall, shift kit, and a few other things upgraded for $1750. Otherwise, a basic stock rebuild will be $1300. As much as I wanted to get the upgraded option I went with the stock rebuild. Yeah I know dropping pulleys and such will blow your trans. Ill see what the guy says about how much power it can handle.
