Patent ID: 8066610

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 torque transmitting mechanism selectively engageable to interconnect the first member of the first planetary gear set with a stationary element; a second torque transmitting mechanism selectively engageable to interconnect the second member of the second planetary gear set with the third member of the third planetary gear set; a third torque transmitting mechanism selectively engageable to interconnect at least one of the third member of the second planetary gear set and the first member of the third planetary gear set with the third member of the third planetary gear set; a fourth torque transmitting mechanism selectively engageable to interconnect the second member of the third planetary gear set with the output member; and a fifth torque transmitting mechanism selectively engageable to interconnect the second member of the fourth planetary gear set with the output member, and wherein the torque transmitting mechanisms are selectively engageable in combinations of at least three to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member.
