At HHP, this HEMITUNER Transmission Control Module is our choice for an aggressive performance based TCM. The most noticeable change users will see are the higher than expected shift points. Features optimized shift schedule and performance tuned AutoStick¨ calibration with automatic upshift in manual gear selection mode. This feature will prevent the transmission from bouncing off the engine's rev limiter in AutoStick¨ mode, preventing possible damage, limp mode or slow shift times for poor track performance. With reduced torque management, drivers should feel firmer, quicker shifts, more power through the shift transitions, higher shift points as well as more transmission control throughout all throttle input levels.
