Abstract
A shift control apparatus for controlling shifting actions of a step-variable automatic transmission having a plurality of selectable groups of forward-drive positions (e.g., normal-spread group and narrow-spread or wide-spread group) having respective different sets of speed ratios, the automatic transmission having an automatic shifting mode in which the shifting actions take place automatically and a manual shifting mode in which the shifting actions are manually controllable, the shift control apparatus including a drive-position-group selecting portion operable upon switching of a shifting mode of the automatic transmission from the automatic shifting mode to the manual shifting mode, to select one of the selectable groups of forward-drive positions in the manual shifting mode, on the basis of the group which was selected last in the automatic shifting mode.
