Abstract
A multiple speed transmission includes an input member, an output member, first, second, third and fourth planetary gearsets each having first, second and third members, and a plurality of interconnecting members each connected between at least one of the first, second, third, and fourth planetary gearsets and at least another of the first, second, third, and fourth planetary gearsets. The transmission includes a plurality of torque-transmitting mechanisms between the input and output members, wherein the torque transmitting mechanisms are selectively engageable in combinations of at least four to establish at least ten forward speed ratios between the input member and the output member.
