PURPOSE: A transmission control method of an automatic transmission is provided to more specifically control the release and coupling of friction elements using various control elements. CONSTITUTION: A throttle opening degree sensor(210) detects the opening degree variation of a throttle valve for delivering a signal of the opening degree variation to a transmission control unit(280). A vehicle speed sensor(220) detects the speed of a vehicle for delivering a signal of the vehicle speed to the transmission control unit. A turbine rotation number sensor(230) detects a current turbine rotation number from the angular displacement of a crankshaft. A fluid pressure sensor(240) detects fluid pressure applied on each friction element. A MG1 rotation number sensor(250) detects the rotation number of a first motor generator(MG1). A MG2 rotation number sensor(260) detects the rotation number of a second motor generator(MG2). A planetary gear set rotation number sensor(270) detects the rotation number of a planetary gear set.
