Patent ID: 8414445

Claim:
A transmission comprising: an input member; an output member; first, second, third and fourth planetary gear sets each having first, second and third members; a plurality of interconnecting members each continuously interconnecting one of the first, second, and third members of the planetary gear sets with another of the first, second, and third members of the planetary gear sets, wherein a first of the plurality of interconnecting members continuously interconnects the second member of the first planetary gear set with the third member of the second planetary gear set, a second of the plurality of interconnecting members continuously interconnects the third member of the first planetary gear set with the second member of the fourth planetary gear set, and a third of the plurality of interconnecting members continuously interconnects the second member of the second planetary gear set with the second member of the third planetary gear set; a plurality of torque transmitting devices each selectively engageable to interconnect one of the first, second, and third members of the planetary gear sets with another of the first, second, and third members of the planetary gear sets, or a stationary member, wherein four of the plurality torque transmitting devices are brakes and two of the plurality torque transmitting devices are clutches, and wherein the torque transmitting devices are selectively engageable in combinations of at least three to establish a plurality of forward speed ratios and at least one reverse speed ratio between the input member and the output member.
