Dual clutch hybrid powershift transmission

A dual-clutch transmission for use in a motor vehicle having an engine and a driveline comprising:

• an input shaft driven by the engine;
• an output shaft adapted for connection to the driveline;
• a planetary gearset in constant driving engagement with said output shaft;
• a first countershaft fixed to a first member of said planetary gearset;
• a second countershaft fixed to a second member of said planetary gearset;
• a first engine clutch operable for establishing a releasable drive connection between said input shaft and a first transfer shaft;
• a second engine clutch operable for establishing a releasable drive connection between said input shaft and a second transfer shaft;
• a first constant mesh gearset driven by said first transfer shaft;
• a second constant mesh gearset driven by said second transfer shaft;
• first and second shift clutches, said first shift clutch operable to releasably drivingly couple said first gearset to said first countershaft, and said second shift clutch operable to releasably drivingly couple said second gearset to said second countershaft;
• and
• a motor selectively drivingly coupled to a third member of said planetary gearset.
