Abstract: A transmission control device detects deterioration of a clutch that can adjust a connection or disconnection state between an engine output shaft and a first input shaft by a pressure of a hydraulic fluid supplied to a first hydraulic chamber. The transmission control device includes a supply control unit that supplies the hydraulic fluid such that the first hydraulic chamber has a predetermined pressure in a state of keeping rotational speed of the engine output shaft constant, a clocking processing unit that measures elapsed time since the supply control unit starts a supply of the hydraulic fluid to the first hydraulic chamber until a rotational speed of the first input shaft exceeds a predetermined rotational speed and determines whether the elapsed time exceeds a predetermined allowed time, and a deterioration determination unit that determines that the first clutch deteriorates in a case where the time elapsed exceeds the allowed time.

Abstract: A clutch-side transmission circuit transmits, from a clutch pedal, a restoring action of the depressed clutch pedal. A switching device connects a first clutch-side hydraulic circuit to the pedal-side hydraulic circuit when a shift lever SL is tilted forwards and connects a second clutch-side hydraulic circuit to the pedal-side hydraulic circuit when the shift lever SL is tilted rearwards. A first clutch is engaged in response to the restoring action of the clutch pedal being transmitted from the first clutch-side transmission circuit. A second clutch is engaged in response to the restoring action of the clutch pedal being transmitted from the second clutch-side transmission circuit.
