Abstract
An automatic transmission comprising a controlling unit for driving and controlling an actuator until a rotation position, which is detected by a potentiometer in response to the receipt of an instruction signal from an operation switch portion , accords with the instructed shifting position. The transmission includes a self-diagnosis unit for diagnosing a trouble after driving the actuator to the position over the instructed shifting position for a predetermined amount on the basis of the first instruction signal by the operation switch portion at a starting time of driving an automobile and after driving the actuator in reverse to the instructed shifting position, as well as driving the actuator by varying high or low the duty ratio in driving and controlling the actuator , in accordance with the judgment whether or not an output signal of the potentiometer corresponds to such driving.
