Patent ID: 8888648

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 the input member is directly interconnected with one of the first, second, and third members of one of the first, second, third, and fourth planetary gear sets and the output member is continuously interconnected with the second member of the fourth planetary gear set and the third member of the third planetary gear set; first, second, third and fourth interconnecting member each continuously interconnecting at least one of the members of the planetary gear sets with at least one other member of the planetary gear sets; and six torque transmitting devices each selectively engageable to interconnect at least one of the first, second, and third members with at least one other of the first members, second members, third members and a stationary member, and wherein at least one of a plurality forward speed ratios and at least one reverse speed ratio is established by the selective engagement of at least three of the torque transmitting devices.
