A shifting control apparatus includes an overall-speed-position shifting control portion including: a synchronous shifting control portion to implement a synchronous control of shifting actions of the vehicular automatic transmission and the step-variable transmission portion to respective target ones of the overall speed positions and the gear positions, such that a moment of generation of a command to establish the target overall speed position is delayed with respect to a moment of generation of a command to establish the target gear position, so that the shifting actions take place in synchronization with each other, irrespective of different control response times of the shifting actions; and a multiple-step shifting control portion to command the synchronous shifting control portion such that the vehicular automatic transmission performs a shift-up action from a present one of the overall speed position to the target overall speed position through at least one intermediate overall speed position intermediate.
