Abstract

An input shaft with plural drive gears and an output shaft with plural driven gears engaging the drive gears forms transmission gear trains. An input clutch transmitting power to the input shaft is between an engine and the input shaft, and a bypass clutch transmitting the power to the output shaft is between the input and output shafts. A changing mechanism changes any of the transmission gear trains in a power transmission state, a steering angle detecting means detects a steering angle of a wheel, and an input clutch control means engagement controls the input clutch. The input clutch control means inhibits a shifting operation in a state of disengaging the input clutch, by inhibiting output of a disengagement signal to the input clutch, in the case that the steering angle is more than an allowable value, and a shifting in a state of engaging no bypass clutch is judged.
