TRANSMISSION CONTROL MODULE PROGRAMMING AND SETUP

The following service procedures require either a programming or a setup event be performed for a complete repair.

Transmission Control Module (TCM) Replacement
If the TCM is replaced, TCM Reprogramming must be performed. Refer to Service Programming System (SPS). See: Vehicle > Programming and Relearning

TCM Reprogramming
If the TCM is reprogrammed, TCM Reprogramming must be performed. Refer to Service Programming System (SPS). See: Vehicle > Programming and Relearning

Ensure the following conditions exist in order to prepare for TCM programming or reprogramming:
- The battery is fully charged.
- The ignition switch is in the RUN position.
- The Techline equipment cable connection at the data link connector (DLC) is secure.

Program the TCM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.

If the TCM fails to program, proceed as follows:
- Ensure the TCM connection is good.
- Inspect the Techline equipment for the latest software version.
- Attempt to program the TCM. If the TCM still cannot be programmed properly, replace the TCM.
