Patent ID: 8157697

Claim:
A transmission comprising: an input member; an output member; a transmission housing; 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 third member of the third planetary gear set; 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 with the first member of the third planetary gear set; a fourth interconnecting member continuously interconnecting the second member of the third planetary gear set with the second member of the fourth planetary gear set; and six torque transmitting mechanisms each selectively engageable to interconnect one of the first, second, and third members with another one of the first members, second members, third members and the transmission housing, and wherein a first of the six torque transmitting mechanisms is selectively engageable to interconnect the second member of the first planetary gear set with the third member of the fourth planetary gear set, a second of the six torque transmitting mechanisms is selectively engageable to interconnect the first member of the fourth planetary gear set with the third member of the fourth planetary gear set, and the torque transmitting mechanisms are selectively engageable in combinations of at least three to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.
