<p>A transmission includes a main shaft, a first input shaft, a second input shaft and a first clutch to drivingly couple the main shaft and the first input shaft. A second clutch drivingly the couples the main shaft and the second input shaft. A first countershaft is driven by a first speed gearset associated with the first input shaft. A second countershaft is driven by a second speed gearset associated with the second input shaft. An output shaft is fixed for rotation with an output gear. A first countershaft gear is driven by the first countershaft. A second countershaft gear is driven by the second countershaft. The first and second countershaft gears are in meshed engagement with the output gear.</p> |
