Beschreibung
Zusammenfassung:	A shift control apparatus for an automatic transmission having an automatic shift mode for performing a shift operation by determining a gear ratio to be set according to a vehicle running condition and a manual shift mode for performing a shift operation instructed by a manual operation by an operator. The shift control apparatus includes a vehicle speed comparing unit for comparing a vehicle speed at the time of inputting a first manual shift command for downshift to a predetermined gear ratio in the manual shift mode and a vehicle speed at the time of inputting a second manual shift command for downshift during a first shift control period from the time of inputting the first manual shift command to the time of completing first shift control according to the first manual shift command, and a successive shift allowing unit for allowing the downshift by the second manual shift command when the vehicle speed comparing unit has determined that the vehicle speed at the time of inputting the second manual shift command is lower than the vehicle speed at the time of inputting the first manual shift command.
