TCM Programming Procedures

  1. The transmission control module (TCM) must be programmed with the proper software/calibrations. Ensure that the following conditions exist in order to prepare for TCM programming:
    • 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.
  2. Program the TCM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.
  3. If the TCM fails to program, proceed as follows:
    • Ensure that the TCM connection is OK.
    • 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.
