Claims

[Scope of utility model registration request]

The automatic transmission controller controls the clutch actuator that engages and releases the clutch, the gear shift unit that switches the gear train of the transmission, and the clutch actuator's clutch disengagement solenoid valve that is turned on only for a time determined by the clutch disengagement timer. a clutch disengagement opening/closing circuit that turns on the clutch engagement solenoid valve of the clutch actuator only for a time determined by the clutch engagement timer; and a manual clutch engagement circuit that selectively triggers the clutch engagement timer and the clutch engagement timer. A multi-stage changeover switch, a first switching contact that applies a reset signal to the reset terminal of the clutch contact timer at any time, and a second switching contact that regulates charging and discharging of the time-limited operation capacitor of the clutch contact timer. and a clutch hold switch, and is configured to interrupt operation of the clutch in the engagement direction by switching the clutch hold switch.
