Abstract:
A transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members, five interconnecting members, and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. Each of the five interconnecting members continuously interconnects at least one of the first, second, and third members of the four planetary gear sets with at least one other of a stationary member, the first, second, and third members of the four planetary gear sets. The torque transmitting devices may include clutches and brakes.
