ABSTRACT:
An automatic transmission control apparatus detects an abrupt loss of signal from the speed sensor due to failure of the speed sensor and shifts the automatic transmission to a higher gear ratio. The control apparatus detects the engine rotation and the position of the shift lever so that when the engine rotation is under a predetermined level the control apparatus allows the automatic transmission to be shifted by the position of the shift lever.
