ABSTRACT:
The present invention discloses a system and a method for easily determining an abnormal operating condition in speed ratios of an automatic transmission by checking a speed ratio that does not perform normally and the condition of the system connected to the speed ratio, if the automatic transmission does not operate normally. The inventive system for determining an abnormal operating condition in speed ratios of an automatic transmission of an automotive vehicle includes a shift lever position sensing member, a turbine rotating frequency sensing member, an output shaft rotating frequency determination, a transmission oil temperature sensing device, a shift controlling member, and a data storing and information display device.
