Circuit/System Description

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module (TCM) high side driver 1 is located inside of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The high side driver 1 provides the voltage for the TCM pressure control solenoids and shift solenoids. This fault is handled inside the TCM and no external circuits are involved.
