Clutch Test: Notes
WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Clutch Test allows a technician to manually select each of the 6 forward ranges with the vehicle stopped. The intent of this procedure is to verify the ability of all 5 clutches to transmit torque without slipping. Refer to the table in Adapt Function , which shows the clutches applied in each gear range.
