A shift control apparatus of an automatic transmissionm which is configured to output changed rotational speed of an input shaft to an output shaft, includes: an input detecting unit configured to detect a real rotational speed of the input shaft; an output detecting unit configured to detect a real rotational speed of the output shaft; an estimating unit configured to estimate an estimated rotational speed of the input shaft, which corresponds to a shift request, by multiplying the real rotational speed of the output shaft by a target gear ratio; and a control unit configured to control the rotation of the input shaft based on a detection result from the input detecting unit. The control unit controls the rotation of the input shaft such that an upper-limiting rotational speed of a variation in real rotational speed of the input shaft is lower than the estimated rotational speed. 种自动变速器的变速控制装置，构成为使输入轴的旋转变速后输出给输出轴，该变速控制装置具有：输入检测部，其检测出输入轴的实际转数；输出检测部，其检测出输出轴的实际转数；推定部，其通过对输出轴的实际转数乘以目标变速比来推定与变速请求相对应的输入轴的推定转数；和控制部
