I recently purchased a TransGo shift kit from Summit. I haven't installed it yet. The instructions aren't that great and the video has little to do with the instructions! This damn kit wasn't cheap either....around $130! I think I just paid for production of that video........anyways, I was wondering what people are using out there in their GN's. I am looking for firm, tire chirping shifts. I actually like harsher shifts...as long as I don't break anything. Which kit has the most bang for the buck? Quality, price, GOOD INSTALL DIRECTIONS, etc? I appreciate any help.
