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