The shift control method for an automatic transmission uses a shift pattern including at least one vehicle-speed-relevant shift line and at least one throttle-opening-relevant shift line for specific gear-shifting depending on a vehicle speed and a throttle opening. The method includes selecting a shift line from the at least one vehicle-speed-relevant shift line and the at least one throttle-opening-relevant shift line, on the basis of a vehicle speed change and a throttle opening change for a predetermined time, and performing a shift control according to the selected shift line.
