Method of operation of a selectable one way clutch selection mechanism

摘要

Apparatus for controlling a selectable one-way clutch (SOWC) in an automatic transmission includes a ring-shaped control housing located substantially concentrically to the SOWC, and an actuation mechanism included within the ring-shaped control housing and effective to actuate a selector plate engaged with the SOWC from a default position to an actuation position. The selector plate is located between the ring-shaped control housing and the SOWC. A hydraulic fluid delivery system hydraulically communicates with the actuation mechanism to control the actuation of the actuation mechanism.
