PURPOSE: A hydraulic impulse of an oil storage system(HIS) of a transmission is provided to supply enough fluid pressure on friction elements of the transmission, thereby improving a package property of a valve body. CONSTITUTION: A plurality of friction elements(1) changes car speed by applying frictional force. A solenoid valve(3) respectively controls fluid pressure applied to the friction elements. A piston slides in a straight line within a case. A spring elastically supports the piston in an oil discharge direction within the case. An HIS(Hydraulic Impulse of an oil storage System) cylinder(5) is installed on a hydraulic line which connects each friction element from the solenoid valve.
