Abstract
A control apparatus controls engaging states of first and second engaging elements selectively engaged with an input shaft during a gearshift operation. During downshift from a relatively high speed ratio to a relatively low speed ratio, the control apparatus controls such that the first engaging element is moved to a position immediately before engagement or to an initial engaging position, rotation speed of the input shaft changes with a first changing rate until a transmission gear system reaches predetermined speed and changes with a second changing rate after that, and when the rotation speed of the input shaft corresponds to that of the relatively low speed, an engaging force of the first engaging element is increased.
