。 A shift set in which a gear is shifted to neutral when a selector is operated to a neutral position, and the rotational speed of the countershaft is accepted as a synchro rotational speed in response to subsequent operation by the selector to select a specific gear position. In a vehicle automatic transmission device that shifts gears to a specific gear when the vehicle becomes included in the range,
It has a first determination reference value and a second determination reference value whose lower limit is larger than the first determination reference value as determination reference values for specifying the shift set area, and in response to a gear shift operation of the selector, a counter is activated. When the rotational speed of the shaft is included in the first determination reference value, a command is given to shift to a specific gear; otherwise, a command is outputted to the engine actuator to make the engine rotational speed variable; An automatic transmission for a vehicle, characterized in that it is provided with a shift change determination means for instructing a gear shift to a specific gear when the rotational speed of the countershaft subsequently becomes included in the second determination reference value.
