PURPOSE: A lubrication control system of an automatic transmission is provided to improve the durability of the automatic transmission by supplying oil to the lubricant part sufficiently regardless of travel condition and operation of a damper clutch. CONSTITUTION: A lubrication control system for an automatic transmission is composed of a torque converter control valve(15) controlling hydraulic pressure from an oil pump with a regulator valve(9) and receiving hydraulic pressure from the regulator valve; a damper clutch control valve(17) supplying and discharging hydraulic pressure from the torque converter control valve through the torque converter to a cooler(33) according to operation of the damper clutch; and a lubricant adjusting valve(35) receiving hydraulic pressure from the cooler by the oil pump, and supplying oil to front and rear lubricant parts. The endurance is improved by sufficiently supplying oil to the lubricant part of the transmission.
