transmission type has been selected, click on "Set Transmission Type."
10. Click "Yes" on the warning box that pops up to start the TCM Replacement Routine.
11. Once the routine is complete, cycle the ignition key off and allow the modules to completely power down to allow the
data to be written into the TCM's memory.
12. Switch the ignition ON (key ON, engine OFF), and verify the correct transmission type in the identification window.
13. Complete transmission and Clutch Learn procedures. While connected to the truck, go to Actions -> Transmission ->
Transmission Learn Procedure.
NOTE: During the transmission learn procedure, the TCM will first learn the clutch values, then the rail, the split,
the range, and finally the gear.
14. Select Learn Transmission and Clutch from the drop down menu at the bottom and click on “Start.”
WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.

WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.
NOTE: If the engine is not started within the allocated time, the gear learn portion of the procedure will fail. If this
occurs, the engine WILL be allowed to start, however the vehicle will be immobile since gear positions were not
learned. If this occurs, simply rerun the test.
15. After the clutch values have been learned, there will be a request to start the engine to continue with the TCM learn
procedure. There is a ten-second window for the engine to start. It is important that the engine is started within this tensecond window. Please follow the prompt to start the engine from the DASH DISPLAY, not the computer.

3 Programming After TCM/AMT Replacement Only

NOTE: While the gear learn portion of the procedure is running, there may be some rocking and jerking of the
vehicle and cab as shifts are made. Always remain in the vehicle while running the transmission learn procedure.
16. Final transmission learn procedure results will display in the information window. At this time, a command will be
given to turn the ignition OFF and wait. There needs to be an adequate amount of time with the key in the OFF position
so the TCM can power down effectively and write the learned values into memory.
17. After a successful memory write, a command will be given to cycle the ignition. Turn the ignition ON. A checkmark
will appear with the text “TCM Learn: Procedure can start”. This indicates that the learn procedure was successfully
performed.

tab.
NOTE: The vehicle needs to be on level ground when viewing or calibrating this data.
