Abstract:
A transmission of the present invention has an input member, an output member, two planetary gear sets, a planetary gear set assembly, 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 planetary gear set assembly includes first, second, third, fourth and fifth members. The torque transmitting devices may include clutches and brakes. The torque transmitting devices are selectively engageable in combinations of at least two to establish at least ten forward speed ratios and at least one reverse speed ratio.
