Abstract
A transmission is provided having a dual clutch to achieve torque flow through a dual countershaft gearing arrangement. The countershaft gearing arrangement includes a plurality of co-planar gear sets having gears that are selectively connectable to a first countershaft and a second countershaft. A transfer gear set transfers torque from the countershafts to an output shaft.
