Abstract:
1. A transmission comprising: an input member; an output member; a planetary gear set assembly having a first member, a second member, a third member and a fourth member; a first planetary gear set having a first, a second and a third member wherein the third member of the first planetary gear set is rotationally fixed to a stationary member; a second planetary gear set having a first, a second and a third member; a first interconnecting member continuously interconnecting the third member of the planetary gear set assembly with the first member of the second planetary gear set; a second interconnecting member continuously interconnecting the fourth member of the planetary gear set assembly with the second member of the second planetary gear set; and at least seven torque transmitting mechanisms selectively engageable to interconnect at least one of the first, second, third and fourth members of the planetary gear set assembly and at least one of the first, second and third members of the first and second planetary gear sets with another of first, second, third and fourth members of the planetary gear set assembly, another of the first, second and third members of the first and second planetary gear sets and the stationary member, and wherein the at least seven torque transmitting mechanisms are selectively engageable in combinations of at least two to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.
