Abstract: PURPOSE: An oil pump rattle noise reduction method is provided to control the rattle noise of an oil pump by controlling a hydraulic circuit which forms the valve body of the oil pump and an auto transmission. CONSTITUTION: A TCU(Transmission Control Unit) executes control which is optimized according to producing conditions. The TCU senses that the location of a transmission range is P or N(S10). The TCU determines whether the oil temperature of ATF(Auto Transmission Fluid) is over than 90 degrees or not(S20). The TCU determines whether an engine cooling fan is off or not when stopping an engine(S30). The TCU increases the line pressure of a hydraulic circuit which is connected to an oil pump to 10bar.
