Abstract: A torque converter (10) translates torque between an internal combustion engine and an automatic transmission. The torque converter (10) includes a rotatable torque input member (20) adapted to be operatively coupled to a crankshaft of the internal combustion engine, and an impeller assembly (12) operatively coupled to rotate with the torque input member (20). The torque converter (10) further includes a turbine assembly (14) and a one-way clutch assembly (62). The turbine assembly (14) is fluidly connected in driven relationship with the impeller assembly (12) and adapted to be coupled to a rotatable transmission input shaft (56). The one-way clutch assembly (62) is disposed radially between the turbine assembly (14) and the transmission input shaft (56).

Abstract: An actuator device for a selectable clutch having three or more clutch modes may include a dual rate piston with a stable middle position. A positive stop provides very accurate control when shifting from an end position to a middle position without overshoot. Precision position control of the actuator device facilitates consistent, stable control of the current mode of the selectable clutch.
