Gen I, II, III Chevrolet Engine 6L80E/6L90E 6 Speed Conversion Kit




The TCM-2650 Gateway will allow you to adapt the GM 6L45E, 6L50E, 6L80E and 6L90E transmission to all previous Generation GM Engines. These GM kits comes with the necessary hardware to directly bolt the transmission to the Gen 1, Gen 2 and Gen 3 engines. We offer either 6L80E and 6L90E (additional core fee) transmissions kits. This kit includes a modified converter that will bolt directly to the existing engine and flexplate. The TCM2650 requires a throttle position signal and and engine RPM in order to make this funcion. WE supply a remote TPS kit if needed. The transmissions internal computer is reprogrammed with a base tune that will get the vehicle drive-able. Any adjustments to shift feel and shift patterns require reprogramming the tCM that is inside the transmissions. This can be accomplished by using HPtuners or EFIlive, just to name a couple. The TCM2650 is more like a gateway/ body control module. They included the following hardware:

  • Transmission
  • Torque Converter
  • TCM-2650 and Harness
  • Remote Throttle Position Sensor (Not needed if Fuel Injection already has one).
  • Base Transmission Tune
