Claim:
1. A transmission comprising: an input member; an output member; a plurality of gear sets, wherein each gear set has a first gear in mesh with a second gear; a plurality of interconnecting members, wherein each of the first gears of each of the plurality of gear sets are fixed for common rotation to one of the plurality of interconnecting members and each of the plurality of interconnecting members are selectively connected to the input member by one of a plurality of torque transmitting mechanisms; a plurality of countershafts, wherein each of the second gears of the plurality of gear sets are selectively connected for common rotation to one of the plurality of countershafts; and a plurality of synchronizer assemblies each selectively coupling one of a pair of the second gears of the plurality of gear sets to one of the plurality of countershafts, and wherein the selective engagement of one of a plurality of torque transmitting mechanisms and one of the plurality of synchronizer assemblies establishes one of a plurality of forward speed ratios between the input member and the output member and a first and a second of the plurality of gear sets each further include a third gear in mesh with the respective first gear and wherein the third gears are selectively connectable for common rotation to one of the plurality of countershafts.
