Savana Trans Noise

Owners of a 2008-2013 GMC Savana equipped with a 4L60E, 4L65E or 4L70E transmission may comment that the transmission makes a squawk or grunt type noise when shifting from 2nd to 3rd gear.

The 3-4 clutch friction (654A) clutch plates along with the Apply Plate (653) and Selective Backing Plate (655) should be replaced.
