PURPOSE: A device and a method for controlling gearshift of an automatic transmission for a car are provided to carry out gearshift by correcting fill time according to a time change. CONSTITUTION: A device for controlling gearshift of an automatic transmission for a car includes a car driving detecting part(100), a gearshift controlling part(200), and a driving part(300). The car driving detecting part detects a car driving condition variably output according to a driving condition of the car. The gearshift controlling part outputs control signal to the car driving detecting part to receive a signal detected by the car driving detecting part, receives a gearshift mode state of the car, a throttle valve opening level, rotational frequency of an output shaft, engine rotational frequency, oil temperature and acceleration pedal operation states, outputs power on up shift duty control signal by a previously set program, and corrects fill time according to a time change.
