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

Control Solenoid Valve Assembly Replacement

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

Transmission Control Module Reprogramming

When transmission control module reprogramming must be performed, refer to Service Programming System (SPS) (Service Programming System (SPS)).

Ensure the following conditions exist in order to prepare for transmission control module programming or reprogramming:
