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.
