ABSTRACT:
A shift control apparatus for controlling shifting actions of a step-variable automatic transmission for a vehicle, which has a plurality of selectable groups of forward-drive positions having respective different sets of speed ratios, each one of the selectable groups of forward-drive positions including at least one high-speed position each having a speed ratio which is different from that of each high-speed position of any other of the selectable groups, the shift control apparatus including a drive-force-increase determining portion operable to determine whether it is necessary to increase a drive force of the vehicle with the automatic transmission placed in any high-speed position, and a drive-position-group selecting portion operable to select one of the selectable groups of forward-drive positions which includes the at least one high-speed position each having the speed ratio higher than that of each high-speed position of any other of the selectable groups, when the drive-force-increase determining portion has determined that it is necessary to increase the drive force of the vehicle with the automatic transmission placed in any high-speed position.
