摘要： A method for controlling a line pressure of an automatic transmission, and controlling the line pressure when oil is supplied to elements of the automatic transmission through hydraulic passages and valves of a valve body at the time of initially starting a vehicle includes a line pressure setting operation of setting the line pressure of the automatic transmission to be equal to or lower than a set pressure when a vehicle is initially started, and a line pressure converting operation of converting the line pressure into a pressure equal to or higher than the set pressure when the automatic transmission is operated for shifting or when a set time has lapsed since initial vehicle starting.
