<p>A control system for a continuously variable transmission 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 control system operates to control the transmission ratio in accordance with a desired ratio including a desired overdrive ratio for providing an overdrive transmission ratio. In a low vehicle speed range, the overdrive transmission ratio is controlled to a value slightly larger than the overdrive transmission ratio.</p> |
