Description

This is the harness only and does not include the controller. The TCM-2650 is designed for situations where a standalone transmission controller cannot control the transmission directly. These mechatronic valve body designs make it nearly impossible to directly control the transmission solenoids with a standalone transmission controller.  The PCS TCM-2650 is an all-in-one solution that will allow the 8L90E transmission with factory controller to be installed in any vehicle with any engine combination and maintain a fully functional transmission. It has been used in many applications and engine combinations, such as Cummin 2.8L, 4BT Diesels, Gen 1 , 2 and 3 GM engines. Whether they are carbureted or Fuel Injected, this system will allow you to use the GM 8 Speeds in practically any vehicle. Comes with a complete harness and the necessary software to program the TCM-2650 Module. The TCM-2600/2650 is used to enable the use of the GM 8l50e and 8l90E transmissions behind practically any engine. all that is needed is a Throttle position signal and Engine RPM.

The TCM-2650 is compatible with 2019 and older GM 8L45E and 8L90E Transmissions.
