ABSTRACT:
An automated triple-clutch multi-speed transmission is adapted to transfer power from the engine to the driveline of a motor vehicle. The transmission includes a first clutch operable for establishing a releasable drive connection between an input shaft and a first shaft, a second clutch operable for establishing a releasable drive connection between the input shaft and a second shaft and a third clutch operable for establishing a releasable drive connection between the input shaft and a third shaft. A first constant mesh gearset is driven by the first shaft. A second constant mesh gearset is driven by the second shaft. A third constant mesh gearset is driven by the third shaft. First, second and third gearset clutches are operable for releasably drivingly coupling the first, second and third gearsets to a countershaft which, in turn, drives an output shaft.
