Reverse Range

When the selector lever is moved to the Reverse (R) position, oil pressure is applied to the input clutch and the reverse and. The drive link, input housing and clutch, and input sprag drive the input sun gear, and the input carrier is held by the reverse band. The input sun gear drives the carrier pinions on their pins and the pinions drive the input internal gear clockwise (opposite the normal direction of rotation). Force from the input internal gear is transmitted to the final drive at a reduction of 2.38:1.
