Transmission Programmers & Tuners

A transmission programming tool functions by sending custom commands via a display to your transmission computer. These commands change line pressure, altering shift firmness dynamic as well as timing. This technology helps increase acceleration with quicker shifting and holding gears longer during wide-open throttle.

Modifying transmission control module programming can lengthen transmission part longevity. This is accomplished by reducing slippage between gearshifts, which also reduces heat and friction, the two greatest enemies to internal transmission components.

A transmission tuner is a handheld device, connected to your vehicle's OBD II port, which allows you to control and optimize transmission behavior and fluid line pressure, modifying the firmness of shifts as well as when the transmission shifts. This results in quicker acceleration by transferring engine power to the wheels faster as well as improved transmission component life.

Depending on the transmission programmer, the directions on tuning will change. However, for most transmission controllers, the first step is to connect it to the OBDII port under the dash of your vehicle. Next, the ignition key is turned to the "on" (with engine off) position. This powers up the programmer. Then follow the instructions and prompts on the display. Once the performance tuner confirms the changes have been made, the key is turned off and the programmer is disconnected. The vehicle can then be started and taken for a test drive.
