Patent ID: 8137232

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; a first interconnecting member continuously interconnecting the third member of the first planetary gear set with third member of the second planetary gear set; a second interconnecting member continuously interconnecting the first member of the first planetary gear set with the third member of the fourth planetary gear set; a third interconnecting member continuously interconnecting the first member of the first planetary gear set with the second member of the second planetary gear set; a fourth interconnecting member continuously interconnecting the first member of the third planetary gear set with the first member of the fourth planetary gear set; a fifth interconnecting member continuously interconnecting the third member of the third planetary gear set with the second member of the fourth planetary gear set; and seven torque transmitting devices each selectively engageable to interconnect 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 the torque transmitting devices are selectively engageable in combinations of at least two to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member.
