Faster line-pressure rise as throttle is increased
Factory-like shift quality during normal driving
Progressively firmer shifts under heavy throttle and wide-open throttle
Designed for towing, performance and heavy-duty applications

TransGo's design modifies the 2-6, 3-5-R and 4-5-6 clutch regulator and boost valve circuits to provide faster, cleaner clutch application and increased holding capacity.
Optional Performance Tuning
For customers looking for more aggressive street-performance characteristics, the kit can also be used in conjunction with HP Tuners or EFI Live to adjust shift-time tables and create more aggressive 1-2 and 2-3 shifts.
