American Made

State-of-the-Art stand-alone transmission controller for the General Motors 4-speed 4L60/65E and 4L80/85E automatics. Fully compatible with carburated, fuel injected and diesel engines. The software download includes several "base" calibrations to start off with for each application.

If you are using a GM 4L60E, it will fit 1996 and newer GM 4L60E transmissions only. (On later model 4L65E models it is not necessary to plug into the input shaft speed sensor.)

If you are using a GM 4L80E, it will fit 1995 and newer GM 4L80E transmissions only. (If earlier unit is desired to be used; the "Bosch" style pressure control solenoid MUST be replaced with the newer "Holley" style pressure control solenoid.

Be sure to click on the "Manual" link and download a copy of the TORC instructions to read about why it is the simplest electronic transmission controller on the market.

If your Controller is 2021 or earlier download 2021. If it's 2022 or newer, download 2022.
