特徴とする自動トランスミツシヨン。 In a transmission that calculates the appropriate gear position and automatically changes the gear position using an actuator to the value obtained by this calculation, when the vehicle is running at low speed, Even if the engine speed changes to a state where it exceeds a downshift line for switching to a starting gear, a means is provided to prevent switching to the starting gear if the engine speed is higher than a predetermined number of rotations. Features automatic transmission.
