ABSTRACT:
A line pressure controller deduces the completion of the speed change operation and sets the line pressure to a low level during the confirmation of the completion. If the acceleration is detected during the confirmation time period, the control device raises the line pressure up to an original level so as to prevent slip of the torque converter.
