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.
A clutch deterioration detection device that detects whether a clutch device including an input shaft, an output shaft and a hydraulic chamber, and being able to adjust a connection or disconnection state between the input shaft and the output shaft by a pressure of hydraulic oil supplied to the hydraulic chamber deteriorates or not, comprising:
