Abstract
A hydraulic control device for a transmission is provided. The hydraulic control device regulates hydraulic pressure from an oil pressure source to generate line pressure, and selectively applies the generated line pressure to at least two kinds of controlled objects. The hydraulic control device includes: linear solenoid valves each controlling hydraulic pressure to the line pressure in accordance with electromagnetic force of a solenoid; and switching valves each selectively switching at least two kinds of controlled objects to apply the hydraulic pressure applied from the corresponding linear solenoid valve to the switched controlled object. The hydraulic control device further includes a feedback oil passage provided for each of the switching valves. The feedback oil passage is branched from one of a plurality of output oil passages of the corresponding switching valve. The feedback oil passage is connected to a feedback port of the linear solenoid valve.
