Patent ID: 8220351

Claim:
A transmission comprising: a transmission housing; a dual clutch assembly having a clutch housing connectable to a flywheel of 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 in mesh with a second 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 reverse gear, a second gear and a third gear, wherein the reverse gear is configured to selectively mesh with both the first gear and the second gear of the sixth gear set; a first transmission input member rotatably supported in the transmission housing and wherein the first gear of the third gear set is selectively connectable for common rotation with the first transmission input member and 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 the first gear of the first and second 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 fourth, and the fifth gear sets are each selectively connectable for common rotation with the countershaft and the second gears of the third and the sixth gear sets are each connected 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 reverse shaft is configured for axial movement and the reverse gear of the sixth gear set is rotatably fixed for common rotation with the reverse shaft; and three synchronizer assemblies for selectively coupling at least one of the gears of the first, second, third, fourth and fifth sets with at least one of the first and second transmission input members and the countershaft, and wherein the 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 five forward speed ratios.
