Abstract
There is provided temporary high-speed gear setting means which causes an automatic transmission to accomplish first-speed gear after it has once been set to second speed gear, for instance, which is selected as a specific high-speed gear upon switching from a non-drive range to the drive range. While it is made possible to manually switch between gear-shifting control operation in automatic mode performed according to preset shifting characteristics and manual mode in which gear-shifting operation is manually performed by a driver, priority is given to accomplishment of the first-speed gear the temporary high-speed gear setting means when the automatic transmission is switched to the manual mode while it is set to the aforementioned specific high-speed gear by the aforementioned temporary high-speed gear setting means.
