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. Laptop software included with 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.

2) Table Select - this allows two different shift tables to be calibrated for one vehicle. Using the included toggle switch; one can simply have a street calibration in Table 1 and a drag strip calibration for Table 2.
3) Speedometer Signal Output - this signal from the TORC module can be calibrated to compensate for tire size changes, third member gear ratio changes and to accurately syncronize an aftermarket speedometer using a GPS device. It can also be calibrated to send the correct signal to most aftermarket Electronic Fuel Injection Systems.
