Patent ID: 8460151

Claim:
A transmission comprising: an input member; an output member; a first, second, third and fourth planetary gear sets each having first, second and third members; a first interconnecting member continuously interconnecting the third member of the first planetary gear set with the first members of the third and fourth planetary gear sets; a second interconnecting member continuously interconnecting the second member of the first planetary gear set with the third member of the second planetary gear set; a third interconnecting member continuously interconnecting the first member of the second planetary gear set and the input member with the second member of the fourth planetary gear set; a first torque transmitting device selectively engageable to interconnect the input member, the first member of the second planetary gear set and second member of the fourth planetary gear set with the second member of the second planetary gear set; a second torque transmitting device selectively engageable to interconnect the second member of the second planetary gear set with the third member of the first planetary gear set and the first members of the third and fourth planetary gear sets; a third torque transmitting device selectively engageable to interconnect the second member of the third planetary gear set and the output member with the third member of the fourth planetary gear set; a fourth torque transmitting device selectively engageable to interconnect the second member of the second planetary gear set with the stationary member; a fifth torque transmitting device selectively engageable to interconnect the first member of the first planetary gear set with the stationary member; and a one-way clutch selectively engageable to interconnect the third member of the third planetary gear set with the stationary member, and wherein the torque transmitting devices are selectively engageable in combinations of at least three and the one-way clutch is engageable between a locked position and an unlocked position to establish at least nine forward speed ratios and at least one reverse speed ratio between the input member and the output member.
