ABSTRACT:
A shift control system of an automatic transmission, wherein first and second transmission sections capable of automatically switching gear stages independently are provided and the first and second transmission sections are shifted to thereby achieve multi-stage shifts, comprising: a device for starting a shift in the second transmission section after the start of a shift in said first transmission section; and a device for ending the shifts in the first and the second transmission sections in synchronism with each other. Even when the first and the second transmission sections are simultaneously shifted, satisfactory shift characteristics are maintained, and further, the suceeding shift control in the second transmission section is adaptively controlled in accordance with the result of the preceding shift, so that the best shift can be achieved regardless of variations in the respective transmission sections.
