Claims

[Scope of utility model registration request]

A torque converter with a mechanical clutch is interposed between the engine and the multi-gear transmission, while a select shift switch detects the lever position of the transmission control lever in the driver's cab, and a hydraulic type that operates the gear shift of the transmission. The select shift actuator selects the select shift actuator based on the ON-OFF switching signal from the select shift actuator and the select shift switch.
Equipped with a relay circuit that opens and closes the shift valve.
The above relay circuit includes a judgment relay that temporarily closes the clutch valve of the hydraulic mechanical clutch actuator of the torque converter during gear shift operation, and a judgment relay that detects a drop in the operating pressure in the mechanical clutch actuator and closes the clutch valve of the hydraulic mechanical clutch actuator. An automatic transmission device for a vehicle, characterized in that it is equipped with a mechanical clutch pressure switch that closes.
