Low/Reverse Rocker Clutch

WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The low/reverse rocker clutch is a OWC which also functions as the low/reverse clutch pressure plate. The low/reverse rocker clutch external splines mate with the case and the internal splines mate with the reverse ring gear/reverse planet assembly.

In 1st and 2nd gears, the center shaft drives the forward cylinder clockwise. The forward clutch is applied and holds the forward ring gear, driving it clockwise. The forward planet provides a counterclockwise resisting torque and the forward/reverse sun gear is driven counterclockwise. The low reverse clutch is released. The low/reverse rocker clutch holds the reverse planet carrier body and allows the forward/reverse sun gear to drive the reverse planet gears which in turn drive the output shaft ring gear and hub assembly. The forward planet and output shaft hub are both splined to the output shaft.

The low/reverse rocker clutch is model dependent. A 5-plate with pressure plates, is used with the 5.4L engine and the 6.0L and 6.8L engines will use a 6-plate configuration.
