Abstract
First and second clutch devices releasably and alternately connect respective transmission input shafts with an engine output shaft. The input shafts are connected through respective sets of transmission gears with a transmission output element. In a gear shift up operation, one of the clutch devices, which has not been in driving engagement, is brought into partial engagement with a first engaging speed for a first period of time, while the second clutch device remains in driving engagement, so that there is a certain period of time overlap wherein both clutch devices are in engagement simultaneously. After the second clutch device has been disengaged, the engagement speed of the first clutch device is decreased to a lower speed and then again increased to a higher speed.
