Description

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.

Applications:

  • 2011-2014 Dodge Charger R/T
  • 2011-2014 Chrysler 300C 5.7L

Requires all engine rev limiters to be set to 6800rpm. 

Do you have a police package? Let us know as your unit will require special programming.  

*DO NOT Initialize TCM with any tool

    TCM 2014 Charger

    This TCM was truly plug and play. I replaced the original differential with a 3.06 and reported it to HHP. After connecting the TCM, everything worked perfectly right away—no check engine lights at all. I still need to adjust the shift points in the PCM, but overall, very satisfied so far.
