A failure detecting system comprises sensor means which monitors preselected parameters representative of vehicle driving condition and thus detects the vehicle condition for driving the vehicle to travel. The sensor means includes one component detecting selector position commanding at least forward or reverse travel of the vehicle. An abnormality is detected on the basis of the vehicular driving condition indicative information provided by the sensor means, which information includes the selector position as detected by the selector position detecting component. In addition, a fail-safe system is responsive to detection of the abnormality by the failure detection system for performing fail-safe operation for controlling the automatic power transmission toward safety side in order to avoid subsidiary failure which otherwise caused by failed component.
