摘要：A device and a method of a hydraulic control system for 4- speeds automatictransmissions which may reduce line pressure in a steady flow during operation of anautomotive vehicle at high speed thereby decreasing the load applied to an oil pump andreducing fuel consumption. And when shifting from the second, third or fourth speed ofthe \"D\" range, where the damper clutch operates, to another shift range, which makes itso the line pressure is not changed when the damper clutch is released therebyincreasing the load applied to the engine, thereby preventing the run-up of the engine,and when the shift is completed, which changes the line pressure again, therebyimproving shift quality and power transmission efficiency.
