Zusammenfassung:	When an overdrive cut is performed to an automatic transmission control when climbing uphill slopes, the actuator position An is stored in overdrive cut aperture storage value C with overdrive cut demands to the automatic transmission executed until the actuator position changes by a first predetermined value Ct1. If the condition C-An>Ct1 is satisfied for a predetermined period of time T0 until timer counter TMR becomes zero, then restoration to overdrive is allowed. Accordingly, even when cruising along long uphill roads, up-shifts to overdrive are prohibited during this time and because there are no up-shifts to overdrive during this time, vehicular speed does not change in fixed periods and thus, a high-level of passenger comfort is achieved.
