ABSTRACT:
A shift control apparatus of a transmission for a vehicle having an input shaft driven by an engine and an output shaft connecting with a drive wheel for automatically changing a speed ratio between the input shaft and the output shaft, comprises accelerator pedal operating amount detecting means for detecting an operating amount of an accelerator pedal, road gradient detecting means for detecting a gradient of a road on which the vehicle travels, vehicle speed detecting means for detecting a vehicle speed, kick-down mode establishing means for establishing a kick-down mode when the operating amount of the accelerator pedal exceeds a threshold value and control means for changing the threshold value based on the road gradient and the vehicle speed.
