Abstract

A transmission is disclosed having an input member, an output member, first, second and third planetary gear sets, a first interconnecting member, a second interconnecting member and six torque-transmitting mechanisms. 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. The planetary gear sets each have first, second and third members. The six torque-transmitting mechanisms are selectively engageable to interconnect one of the first, second, and third members with another of the first, second, and third members.
