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 actuatable in combinations of four 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 at least 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.
