ABSTRACT:
A control system for a continuously variable transmission for a motor vehicle has a transmission ratio control valve having a spool for controlling oil supplied to a cylinder of a drive pulley to change the transmission ratio. The transmission ratio control valve has chambers at both ends of the spool. By controlling flow rate of oil supplied to the chambers in accordance with a desired transmission ratio, the spool is shifted, so that the transmission ratio changing speed is controlled. When an accelerator pedal of the vehicle is rapidly depressed while the transmission ratio is changing, the transmission ratio changing speed is reduced for a predetermined time.
