Page 6: Installation Steps
Installation Steps: Transmission Harness 1. Start by removing the system from the box and carefully laying it across a workbench or table. Take notice of the loomed transmission harness which contains the round transmission connector and vehicle speed sensor connector. These are the only two connections needed for both 4L60E (65E) or a 4L80E (85E) transmissions. - Page 7 Install Picture 2 – VSS (Vehicle Speed Sensor) Connector Figure 1 – Transmission Harness Connections on Transmission...

Page 11: Vehicle Harness
Installation Steps: Vehicle Harness 1. The Vehicle Harness has a 16 pin connector that plugs into the left side of the TORC Module. See Figure 2 on page 8 for the connection. See Diagram 3 on page 15 for a diagram identifying the wires in this connector. 2. - Page 12 B. Black Wire(s) Labeled – “Module Ground” & “TPS Ground” Connection of these wires will depend on what type of throttle position sensor you are using: one that is part of an EFI system or one fitted to a carburetor or mechanically injected diesel engine. Electronic Fuel Injection Systems Splice both, “MODULE”...
- Page 13 C. Green Wire Labeled – “Throttle Position Sensor Signal” Connection of this wire will depend on what type of throttle position sensor you are using: one that is part of an EFI system or one fitted to a carburetor Electronic Fuel Injection Systems Connect this wire to the Throttle Position Sensor signal on a “Throttle-By- Cable”...
- Page 14 Identifying the Terminals of an Unknown Throttle Position Sensor This is a procedure for identifying the correct terminal connections of any potentiometer-style throttle position sensor (almost all three-terminal TP sensors). A DVOM or analog Ohmmeter is required. 1. Set the meter to resistance mode and set it to a scale that can read up to 10K or 20K Ohms (if it is not auto-ranging).
- Page 16 Optional Accessories within the TORC Module E. Tan Wire printed – “Speedometer Signal Output” We have provided an adjustable speed signal output on the tan wire on pin 12 of the vehicle connector that can be used to drive an electronic speedometer.
- Page 17 F. Yellow Wire printed – “Engine RPM Input” This is not a signal to operate a tachometer, but the same signal from your ignition system that operates a tachometer. The engine RPM signal input on the yellow lead (pin 7) can be connected to a digital tachometer output from an engine computer or the tachometer output from an MSD ignition or similar CDI (Capacitive Discharge Ignition) system, but NEVER to the coil outputs (coil negative stud) of a CDI system...

Page 18: Setting Up The Module
SETTING UP THE TORC MODULE Software Due to the growing number of PCs lacking a CD drive, the software is not included with this kit, but rather downloadable to a Windows PC from the 66501 product page on the Painless website. You will need the “Second Generation Software”... - Page 19 If needed, you can manually adjust TPS values by choosing “Adjust Idle” or “Adjust WOT” in the TPS setup menu. Once the TPS calibration procedure is completed, the values are permanently stored in the controller and will be active for every tune written. TPS values displayed within individual tunes are then irrelevant.
- Page 20 BUILT-IN DISPLAY The second generation built-in display of the Torc is easier to use and more intuitive than our previous module. It provides useful information, such as current speed, gear, transmission temperature, and TCC lock status, along with any fault messages. Using the menus, you’ll be able to access many of the same options found in Shiftware.
- Page 21 Home Screen Normal Mode Home Screen Enlarged Mode...
- Page 22 MAIN MENU Home Screen = Chooses the home screen as your default view. Info Screen = Shows current sensor values, replacing the home screen as default view. Info includes TPS voltage and percentage, battery voltage, commanded pressure in PSI, and engine RPM. Setup Menu = Use this menu to choose preliminary settings essential for operating the vehicle.
- Page 23 Speed Sensor = This menu allows you to choose your speed sensor type and configure its details such as speedometer drive gear teeth, driven gear teeth, and pulses per revolution. Rotating the knob in this screen changes the speed sensor type. Available speed sensor types will vary depending on the current transmission type.
- Page 24 TUNE MENU Shift Points = Sets the RPM at which shifts occur for all shifts. You will be presented with a menu showing 10% throttle, 40% throttle, and Wide Open Throttle. Under each is shown shift point RPM. You can adjust each throttle percentage individually.
- Page 25 Override = There are several options in this menu which are useful when troubleshooting. “Line Prs” can be used to override line pressure manually. Use this only if you were instructed to do so by a Painless technician. “TCC Sol” can be used to manually lock the TCC by holding the knob down. When released, the TCC will unlock.

Page 26: Shiftware Software
SHIFTWARE SOFTWARE Introduction Using the Shiftware software allows you to modify the way your Torc Transmission Control System behaves. You can customize shift-points as well as monitor and diagnose the Torc unit in real-time. Setup To create a calibration for the Torc module, it is best to start with one of the standard calibrations which are included with the software. - Page 27 Customize The main window is where all of the shift points and line pressure editing is done. The graph displays the up-shift and down-shift speeds in relation to throttle position for each shift. It also displays the line pressure & firmness curve in relation to throttle position.
- Page 28 If Select Pairs Together is enabled, then the corresponding down-shift point will be automatically selected along with the up-shift point. This can be turned off by clicking the checkbox on the right. You can select multiple points by holding CTRL while clicking the points or a range of points by holding SHIFT and clicking the two points on each end.
- Page 29 Once you have created your calibration, you can save the file to your hard drive or an external storage device. To save, click the Save button on the toolbar. Then, browse to the location where you want it saved and click Save. Use “Save As”...
- Page 30 Also note that torque converter slip at low speeds renders engine RPM values meaningless. It is usually desirable to have light-throttle shift points within a low RPM range. In this case, it is best to base light-throttle shift points on vehicle speed rather than engine RPM (as most auto manufacturers do).
