ABSTRACT:
A transmission is provided having an input member, an output member, first, second, and third planetary gear sets each having first, second and third members. The input member is continuously interconnected to the third member of the third planetary gear set and the output member is continuously interconnected to the third member of the first planetary gear set. The transmission further includes six torque transmitting mechanisms selectively engageable to interconnect one of the first, second, and third members with at least one other of the first, second, third members, and a stationary element. The 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.
