Abstract
A hydraulic control apparatus for controlling a line pressure utilized in a continuously variable transmission. The apparatus controls the amount of line pressure supplied to be as small as possible without resulting in any slippage between a belt member which spans the pulleys. The apparatus monitors torque on the input shaft and output shaft to determine if any slippage is occurring.
