Patent ID: 8038567

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 first rotary member formed by directly connecting the third member of the first planetary gear set with the second member of the third planetary gear set; a second rotary member formed by directly connecting the first member of the second planetary gear set with the first member of the third planetary gear set; a third rotary member formed by directly connecting the third member of the third planetary gear set with the first member of the fourth planetary gear set; and five torque transmitting devices each selectively engageable to interconnect one of the first members, second members, third members, first rotary member, second rotary member, and third rotary member with at least one of another of the first members, second members, third members, first rotary member, second rotary member, third rotary member, and a stationary member, and wherein the torque transmitting devices are selectively engageable to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member, and wherein at least two torque transmitting devices are disengaged in each of the at least eight forward speed ratios and the at least one reverse speed ratio.
