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

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.
