ABSTRACT:
There is disclosed a line pressure control for an automatic transmission of an automotive vehicle wherein the automatic transmission is drivingly coupled with the engine and transmits the engine torque by a hydraulically actuable coupling which is actuable by a pressurized hydraulic fluid which is as high as the line pressure. According to this control, a predetermined pattern of variation of the pressurized hydraulic fluid is changed to a second pattern upon detecting the occurrence of a change in an engine load beyond a predetermined degree, and the pressurized hydraulic fluid follows the second pattern temporarily, i.e., for a period of time.
