Circuit/System Description

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module (TCM) temperature sensor is located inside of the TCM. The TCM is located within the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The TCM temperature sensor provides the TCM temperature. This temperature reading is used in various shifting and diagnostic routines in the TCM software.
