An input shaft (12) is provided with a plurality of drive gears (21-26), an output shaft (14) is provided with a plurality of driven gears (31-36) respectively engaging with the drive gears, and transmission gear trains are formed by the respective engaged gears. An input clutch (15) for transmitting a power to the input shaft is provided between an engine and the input shaft, and a bypass clutch (50) for transmitting the power to the output shaft is provided between the input shaft and the output shaft. The apparatus is provided with a changing mechanism for changing any one of the transmission gear trains in a power transmission state, a steering angle detecting means for detecting a steering angle of a wheel, and an input clutch control means for engagement controlling the input clutch. The input clutch control means inhibits a shifting operation in a state of disengaging the input clutch in a step S8, by inhibiting an output of a disengagement signal to the input clutch, in the case that the steering angle is more than an allowable value in a step S5, and a shifting in a state of engaging no bypass clutch is judged in a step S7. |
