PURPOSE:To make it possible to detect the output rotation speed accurately, by setting a rotation speed detecting means at subchange gear, and converting the rotation speed of an input shaft of subchange gear into an electric signal. CONSTITUTION:An electronic controller 500 performs current controlling of solenoid valves S1-S4 of an oil pressure controller and a transfer controller. This electronic controller 500 is constituted of such as an automatic change gear shift lever position sensor 510 which detects the set range position of a four speeds automatic change gear, converts a signal detected from the transfer output shaft rotation speed into the travelling speed, and detects the acceleration quantity through a throttle opening sensor 540. That is, as the electronic controller 500 detects the rotation speed of the output shaft through a rotation speed sensor 550, accurate output rotation speed can be detected.
