I'm about to have my tranny built with a stout shift kit and a TCI 3k. The guy isn't replacing any shafts or gears. Does anybody know anything about the TCI stall and how well they perform and also who has a built 4L60E tranny and has it given you any problems. I just want to make sure that I dont have problems because I dont plan on putting a lot of power to the wheels............................................ ...YET.
