Patent ID: 8343005

Claim:
A transmission comprising: an input member; an output member; a first planetary gear set having a first, a second and a third member; a second planetary gear set having a first, a second and a third member; a third planetary gear set having a first, a second and a third member; a fourth planetary gear set having a first, a second and a third member; a first interconnecting member continuously interconnecting the first member of the first planetary gear set with the first member of the second planetary gear set; a second interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set; a third interconnecting member continuously interconnecting the third member of the second planetary gear set with the second member of the fourth planetary gear set; a fourth interconnecting member continuously interconnecting the second member of the third planetary gear set with second member of the fourth planetary gear set; and at least six torque transmitting mechanisms each selectively engageable to interconnect at least one of the first, second and third members of the first, second, third and fourth planetary gear sets with another of the first, second and third members of the first, second, third and fourth planetary gear sets and a stationary member, and wherein the at least six 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.
