Patent ID: 8360922

Claim:
A multi-speed transmission comprising: an input member; an output member; a stationary member; a first and a second compound planetary gear set; wherein the first compound planetary gear set has a first, a second, a third, a fourth, and a fifth member; wherein the second compound planetary gear set has a first, a second, a third, and a fourth member; wherein the members of the planetary gear sets are sun gear members, ring gear members and carrier members; wherein the first member of the second compound planetary gear set is continuously connected for common rotation with the output member; wherein the second member of the second compound planetary gear set is continuously grounded to the stationary member; wherein none of the members of the first planetary gear set are continuously connected for common rotation with any of the members of the second planetary gear set; and seven torque-transmitting mechanisms selectively engagable to interconnect respective ones of the members of the first compound planetary gear set with the input member, the stationary member or respective ones of the members of the second compound planetary gear set, the seven torque-transmitting mechanisms being engagable in combinations of three to establish up to ten forward speed ratios and a reverse speed ratio between the input member and the output member.
