Okay, my bud has a 2002 GT Auto, Bullit Rims, stripes, leather, etc. So far we have installed a cold air intake and a 75 shot dry kit. It screams (hopefully it won't run lean before i can get the air fuel guage sorted out) but I'm worried about his tranny. Is the GT Auto tranny durable? What HP range? Should he get a cat back next, gears, X-pipe, H-pipe, or a torque converter? Does he need a tranny cooler? Lots of questions, thanks guys. Great board.
