装置。 A clutch actuator for intermittent operation of a friction clutch connected to the engine, a gear shift unit for switching the gear train of a gear type transmission connected to the friction clutch, and each of automatic gear, manual gear, and multiple neutral gears. A gear change switch that is selectively switched to a command position and outputs an output, an accelerator sensor that outputs accelerator opening information, a vehicle speed sensor that outputs vehicle speed information, and when the vehicle speed falls below a set value and returns to the start control range. An automatic transmission for a vehicle is provided with a control means for performing start control in place of shift control, wherein one of the plurality of neutral gears of the shift switch is set to a hold gear command position, and the control means When the input changes from the automatic gear shift command to the hold gear command, the current gear is held, and when the vehicle speed returns from the shift control area to the start control area, a start process is started at the set start gear. An automatic transmission device for vehicles.
