WARNING: This page is about a different car, the 2012 GMC Yukon, 2012 Chevrolet Tahoe, and 2012 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module monitors the 1-3 clutch slip speed when the 1-3 clutch is applied. The 1-3 clutch is displayed as Clutch 4 on the scan tool. The transmission control module is part of the control solenoid valve assembly and is not serviced separately.
