Abstract:
1. A transmission comprising: an input member; an output member; a first, second, third, fourth, and fifth gear set each having a first gear, a second gear, and a third gear wherein the output member is continuously connected with one of the gear sets; a first interconnecting member continuously connected to the third and fourth gear sets; a second interconnecting member continuously connected with the first and second gear sets; a first countershaft continuously connected to the fifth gear set; a second countershaft continuously connected to the fifth gear set; a dual clutch assembly selectively engageable to interconnect the input member with one of the first interconnecting member and the second interconnecting member; and four synchronizer assemblies each selectively coupling one of the first, second, third, and fourth gear sets with at least one of the first interconnecting member, the second interconnecting member, the first countershaft, and the second countershaft, and wherein the dual clutch assembly and four synchronizer assemblies are selectively engageable in combinations of at least two to establish at least seven forward speed ratios and at least one reverse speed ratio between the input member and the output member and wherein the first gear, second gear, and third gear within each of the first, second, third, fourth, and fifth gear sets are co-planar.
