WARNING: This page is about a different variant/trim than selected.

The transmission control module (TCM) high side driver 2 is located inside of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The high side driver 2 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.
