Patent ID: 8505400

Claim:
A transmission comprising: a transmission housing; a dual clutch assembly having a clutch housing connectable to an engine, wherein the clutch housing is rotationally supported within the transmission housing; a first, second, third, fourth, fifth and sixth gear set, wherein the first gear set includes a first gear and a second gear in mesh with a third gear, the second gear set includes a first gear in mesh with a second gear, the third gear set includes a first gear in mesh with a second gear, the fourth gear set includes a first gear in mesh with a second gear, the fifth gear set includes a first gear in mesh with a second gear and a sixth gear set includes a first gear in mesh with a second gear; a first transmission input member rotatably supported in the transmission housing and wherein each of the first gears of the fourth, fifth and sixth gear sets are rotatably fixed for common rotation with the first transmission input member; a second transmission input member rotatably supported in the transmission housing, wherein each of the first gears of the first, second and third gear sets are rotatably fixed for common rotation with the second transmission input member and wherein the second transmission input member is concentric with the first transmission input member and at least partially surrounds the first transmission input member; a countershaft rotatably supported within the transmission housing and spaced apart from and parallel with the first and second transmission input members, wherein the second gears of the first, the second, the third, the fourth, the fifth and the sixth gear sets are each selectively connectable for common rotation with the countershaft; a reverse shaft rotatably supported within the transmission housing and spaced apart from and parallel with the first and second transmission input members, wherein the third gear of the first gear set is rotatably fixed for common rotation with the reverse shaft; three synchronizer assemblies each selectively coupling at least one of the second gears of the first, second, third, fourth, fifth and sixth gear sets with the countershaft, and wherein a first of the three synchronizer assemblies selectively connects at least one of the second gear of the first gear set and the second gear of the second gear set to the countershaft shaft, and wherein the combined selective engagement of dual clutch assembly interconnects the dual clutch housing with at least one of the first and the second transmission input members and the selective engagement of at least one of the three synchronizer assemblies establishes at least one of a first, a second, a third, a fourth, and a fifth forward speed ratios.
