Abstract
A transmission for a motor vehicle with an engine includes a transmission housing and a dual clutch assembly with a clutch housing connectable to an engine output member. The clutch housing is rotationally supported within the transmission housing. The selective engagement of the dual clutch assembly interconnects the dual clutch housing with at least one of a first input member and a second input member. The transmission also includes a plurality of gear sets associated with various forward and reverse gear ratios, a controller implemented with an algorithm that provides a lock-up profile for the dual clutch assembly, and a plurality of synchronizer assemblies that couple at least one of the gear sets with at least one of a first countershaft and a second countershaft. The selective engagement of at least one of the synchronizer assemblies establishes at least one of the forward speed ratios.
