WARNING: This page is about a different car, the 2011 GMC Yukon, 2011 Chevrolet Tahoe, and 2011 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module monitors the hybrid low, 1-2 clutch slip speed when the hybrid low, 1-2 clutch is applied. The hybrid low, 1-2 clutch is displayed as Clutch 1 on the scan tool. The transmission control module is part of the control solenoid valve assembly and is not serviced separately.
