Abstract

A control device 5 for an automatic transmission apparatus 2 has an automatic gearshift mode in which the gear of the automatic transmission 2 is automatically controlled by setting the shift position of a shift device 3 in one of forward travel positions including a first and a second forward position. The control device 5 also has a manual gearshift mode changing the gear one step by one step by an operating unit 4 other than the shift device 3 while maintaining the shift position set in the forward position 33. The manual gearshift mode includes a first manual mode when the shift position of the shift device 3 is set in a first forward position, and a second manual mode when the shift position is set in a second forward position. A control pattern of the first manual mode differs from that in the second manual mode.
