Rocker Clutch, Reverse Clutch, Reverse Planetary Assembly
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The rocker clutch designs are used in the low/reverse and are model dependent. The low/reverse rocker design has captured reverse friction and separator plates which must be serviced using a new rocker assembly. When installed, the internal splined portion of the rocker clutch assembly should rotate clockwise and lock when rotated counterclockwise.
