  • $875.00

The PCS TCM-2650 is a pass-thru device that allows you to install a modern GM transmission into almost any vehicle. It is required due to the fact you have to take analog inputs (RPM  and Throttle position at a minimum), and convert them into CAN bus data to send to the transmission for it to function.For the 6.2 and 6.5L diesels, transmissions that can be used with this controller include the following:

  • GM 6L80E 6 Speed Automatic
  • GM 6L90E 6 Speed Automatic

On top of basic functionality, this unit also enables other inputs to be added such as:

  • Tap Shifting (TUTD)
  • Tow/Haul Mode
  • Manual Mode
  • Dyno Mode
  • Torque Converter Lockup Override

This kit Includes:

  • TCM-2650 Module
  • Pre-terminated, labeled, wire harness

Note, you will also need the HP Tuners interface to program the actual TCM inside the transmission. This can be found in our other listings.
