Section 1585 (68RFE Automatic Transmission - (Service Information) - 2500 Hd): Clutch: Inspection
WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
Verify that the overrunning clutch assembly turns smoothly in one direction, and locks in the opposite direction. Verify that the oil feed holes in the inner race are not blocked by debris.
Replace the LR clutch retainer if the piston bores or bushing surfaces are badly scored, worn or damaged.
