Abstract: A transmission has an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Two of the four planetary gear sets are stacked. Two of the planetary gear sets include first, second and third members. The two planetary gear sets that are stacked form a planetary gear set assembly that includes a first, second, third and fourth member. The torque transmitting devices include clutches and brakes.
