What’s the difference between a Shift Kit and a Reprogramming Kit?

The purpose of a TransGo Shift Kit® valve body repair kit is to reduce, prevent and correct complaints such as shift irregularities or durability issues. Shift Kit® valve body repair kits are perfect for normal everyday use and light duty towing.

TransGo Reprogramming Kit™ valve body kits are designed for performance. Most contain additional features like;

  • Gear Command

  • Tow/Haul
    Product is designed for use in hard working vehicles that tow or haul heavy loads.
  • Performance
    Product is intended for high performance vehicles.
  • Tuneless
    Patent-pending internal calibration technology “tuneless” allows install without the need for additional transmission tuning software or programmers.

In summary:

If you are looking to retain shift comfort but want added durability, use a TransGo Shift Kit® valve body repair kit. For performance shifts without sacrificing durability use TransGo Reprogramming Kit™ valve body kits.
