Abstract
A vehicle transmission has a first torque transmission path for transmitting a torque from the engine to an output shaft of the transmission through a first input shaft of the transmission, a first pair of gears and a first mesh type clutch. A second torque transmission path transmits a torque from the engine to the output shaft through the first input shaft, a second pair of gears and a second mesh type clutch. A third torque transmission path transmits a torque from the engine to the output shaft through a second input shaft of the transmission, a friction clutch disposed between the second input shaft and the engine, a third pair of gears and a third mesh type clutch. The torque transmission path from the engine to the output shaft shifts in order of the first torque transmission path, the third torque transmission path, and the second torque transmission path. When the torque is transmitted through the third torque transmission path, a torque at the first input shaft is controlled.
