NOTE

Refer to Torque Path in Reverse Range, Converter Drive, Right Steer and Hydraulic System,

Reverse Range, Converter Drive, Right Steer Schematic Views.

Refer to Torque Path in Reverse Range, Converter Drive, No Steer for the action of range gearing in reverse range.

Steer action in reverse is described in the following paragraphs.

As in all steer conditions, counterclockwise rotation is delivered to the right and left steer--clutch drive gears by the

steer gear system. Unlike steer in forward ranges, the steer clutch opposite the side toward which steer is desired

must be applied. Thus, for right steer in reverse, the left steer clutch must be engaged. This is because both the ring

gear and sun gear turn in the same direction in reverse operation. Thus, the transmission output speed is increased

at that side and decreased at the opposite side. Steer is always towards the side at which output speed is lower, re-

gardless of vehicle direction. The steer flywheel functions are explained in Torque Path in High Range, Lockup Drive,

Left Steer.

Refer to this work package for the gear ratios involved in reverse range steer.
