PURPOSE: A shifting control method of a vehicle is provided to reduce shift shock and to improve responsiveness and shift quality in power-on downshifting from the 2-range into 1-range by compensating and learning downshifting. CONSTITUTION: Travel state is decided by detecting the travel detection signal of a vehicle, and downshifting from the 2-range into the 1-range is decided in satisfying the predetermined condition(S10-S60). A throttle position sensor signal is read in downshifting from the 2-range into the 1-range, and variables are set and a pressure control solenoid signal is output(S70-S100). Time is counted by deciding the end time of first shifting, and pressure is regulated after outputting solenoid valve control signals for first and second shift control(S110-S150). Solenoid valve signals for first and second shift control are output in detecting downshifting from the 3-range into the 1-range, and time is counted(S160-S180). The solenoid valve control signal for regulating pressure is output in case of count-time to be over the predetermined time, and time is counted in finishing shifting from the 3-range into the 2-range(S190-S230).
