A drain system for a torque converter may include a hydraulic drain path draining the oil used in the torque converter to the transmission, a hydraulic control path adapted to transmit the oil discharged out of the hydraulic pump to the hydraulic drain path, and a switch valve disposed at the hydraulic drain path, and adapted to operate by pressure of the oil supplied through the hydraulic control path, wherein the switch valve may selectively open/close the hydraulic drain path. |
