This abstract first appeared for US patent application 18499709 titled 'ANTI-ROTATE PISTON FOR VEHICLE TRANSMISSION
Original Abstract Submitted
A transmission includes a housing defining an actuator cavity, a plurality of clutches disposed within the housing and configured to be engaged in various combinations to generate gear ratios corresponding to forward speeds of the transmission, and an actuator assembly configured to selectively engage one clutch of the plurality of clutches, the actuator assembly including a piston slidingly disposed within the actuator cavity. An anti-rotation assembly is configured to prevent rotation of the piston within the actuator cavity, the anti-rotation assembly including a stop and a projection. The projection is coupled to and extends outwardly from an interior surface of the piston, and the stop is grounded to the housing and includes a bore configured to receive a distal end of the projection to thereby prevent rotation of the projection and piston.
