A control system for a continuously variable transmission for a motor vehicle has a line pressure control valve having a spool for controlling oil supplied to a cylinder of a driven pulley to change the transmission ratio. The control system operates to increase the line pressure when the vehicle stops. The increased line pressure actuate the cylinder thereby increasing the transmission ratio.

A control system for a continuously variable transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. The line pressure control valve has chambers. When the transmission ratio reaches a maximum value after disengagement of a clutch, a line pressure reducing signal gen...
