Control Solenoid Valve and Transmission Control Module Assembly Programming and Setup 2ML70

The following service procedures require either a programming or a setup event be performed for a complete repair. The transmission control module (TCM) is part of the control solenoid (w/body and TCM) valve assembly, and is not serviced separately.

Transmission Control Module (TCM) Replacement

If the TCM is replaced, TCM Reprogramming must be performed. Refer to Service Programming System (SPS) .

TCM Reprogramming

When TCM Reprogramming must be performed, refer to Service Programming System (SPS) .

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 DLC and TCM connections are 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.

TCM Setup

This device requires no setup.
