Abstract: A shift controller controls a downshift to a low shift speed, spaced apart from a high shift speed by two or more steps, through an intermediate shift speed, by first releasing first and second shift release elements, then engaging a first shift engagement element, and finally engaging a second shift engagement element, while controlling the torque capacity of the second shift release element by feedback control. As a result of releasing the first and second shift release elements before engaging the first shift engagement element, it is possible to rev up an input rotation at maximum performance of an engine to reduce the time for shifting. As a result of the feedback control of the torque capacity of the second shift release element after engaging the first shift engagement element, a torque fluctuation at the intermediate shift speed can be reduced to avoid occurrence of an uncomfortable shift shock.
