Abstract: A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes including a selectable one-way clutch actuatable in combinations of two to establish a plurality of forward gear ratios and one reverse gear ratio. The transmission also includes a transmission auto start/stop enabler which includes a latch mechanism. The latch mechanism readies one of the plurality of torque transmitting devices during an engine auto stop/start event or in preparation for a stop of the motor vehicle.

Abstract: An assembly includes a valve body having an inlet in selective communication with an outlet and having an unlatch port, a latching piston disposed within the valve body, a balance spring disposed between the latching piston and the valve body, and a valve piston disposed within the valve body. The inlet communicates with the outlet when the valve piston is in a first position and the inlet does not communicate with the outlet when the valve piston is in a second position. A diaphragm spring is disposed between the latching piston and the valve piston. A holding spring is disposed between the valve piston and the valve body. An unlatching mechanism is in communication with the unlatch port of the valve body.

Abstract: A three mode continuously variable transmission (CVT) for a motor vehicle includes an optional speed change device connected to a pulley and a belt assembly or other continuously variable unit. The pulley and belt assembly is also connected to a planetary gear set arrangement. The planetary gear set arrangement generally includes two planetary gear sets, two brakes and two clutches. The planetary gear set arrangement is connected to a final drive unit. Engagement of the clutches and brakes provides three modes of operation to the CVT.
