GM Turbo 200-4R Transmission High Performance Valve Body Shift Kit
by Superior Transmission Parts
This shift correction package is designed for the street rodder. You can expect the best of both worlds. Clean shifting under normal throttle and much firmer, very positive shifts under heavy throttle. This kit also corrects the proper shift timing in TH200-4R transmissions.
Includes a 0.471'' boost valve.
