A shift control system for an automatic transmission may include: a shift speed detector for detecting a current shift speed; a kick-down switch for detecting demand for a kick-down shift; and a control portion completing a shift to a target shift speed according to a predetermined shift pattern before a shift finish point by modifying control duties of off-going and on-coming elements if a shift pattern of a lower shift speed, a gear ratio of which is higher than that of the target shift speed, is passed during the kick-down shift, and then performing a shift to the lower shift speed.
