Rocker Clutch, Reverse Clutch, Reverse Planetary Assembly
WARNING: This page is about a different car, the 2012 Ford F550 Super Duty and 2012 Ford F450 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.
