Patent ID: 8435153

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, wherein at least one of the first, second, and third members is directly connected to at least one other of the first, second, and third members to form each of at least a first, a second, and a third rotary member; a first torque transmitting device selectively engageable to connect the first rotary member with the second member of the fourth planetary gear set; a second torque transmitting device selectively engageable to connect the second member of the second planetary gear set with the first member of the fourth planetary gear set; a third torque transmitting device selectively engageable to connect the second rotary member with a stationary member; a fourth torque transmitting device selectively engageable to connect the third member of the first planetary gear set with the stationary member; a fifth torque transmitting device selectively engageable to connect the second member of the fourth planetary gear set with the stationary member; and a sixth torque transmitting device selectively engageable to connect the third rotary member with the stationary member, and wherein the torque transmitting devices are selectively engageable to establish a plurality of forward speed ratios and at least one reverse speed ratio between the input member and the output member, and wherein at least four torque transmitting devices are disengaged in each of the plurality of forward speed ratios and the at least one reverse speed ratio.
