摘要： A hydraulic circuit for a transmission includes a friction element that engages or disengages an operating element of the transmission, a pump that pumps oil to form preliminary pressure that allows the friction element to be maintained in a standby state in which the friction element is ready to operate, and a direct control valve that receives the oil that has passed through the pump and adjusts the preliminary pressure to form operating pressure that allows the friction element to operate, when operating the friction element. The friction element includes a hydraulic chamber into which the oil is introduced, a first supply hole through which the oil that has passed through the pump is supplied to the hydraulic chamber, and a second supply hole through which the oil that has passed through the direct control valve is supplied to the hydraulic chamber.
