ABSTRACT:
A low inertia clutch and gear assembly for disposition on a countershaft of a dual clutch automatic transmission (DCT) includes a gear which is in constant mesh with a gear secured to the input shaft of the transmission and which is freely rotatably disposed on one of the countershafts or lay shafts. The lower inertia components of the clutch, i.e., the clutch hub and the smaller diameter friction plates are secured to the countershaft whereas the higher inertia components, i.e., the clutch housing, the larger diameter friction plates, the reaction plate, the piston and the return springs, rotate with the gear.
