ABSTRACT:
In an electronically controlled automatic transmission, when it determines that the position of the selector lever is located at a position other than a neutral position, it compares the time varying ratio of the number of revolutions of the output shaft with a first prescribed value, and when it determines that the time varying ratio is greater than the first prescribed value, a control device performs a temporary gear change prohibiting process to temporarily prohibit a gear change of the automatic transmission. Accordingly, an abnormal state of an output shaft revolution sensor can be sensed without the provision of a vehicle speed reed switch.
