ABSTRACT:
A control system for an automatic power transmission monitors atmospheric pressure and a throttle valve open angle. The system corrects the monitored throttle valve open angle on the basis of the monitored atmospheric pressure so as to compensate for a drop of engine output torque due to lowering of the atmospheric pressure. The corrected throttle valve open angle is used for performing shift control and/or line pressure control.
