    摘要: In a gearshift control apparatus for an automatic transmission wherein the torque capacity of a release side clutch is gradually lowered, and the torque capacity of an engagement side clutch is gradually raised, whereby the release side clutch and the engagement side clutch are changed-over to effect a clutch-to-clutch gearshift; control means issues two control commands to the engagement side hydraulic control mechanism in a term which extends until an inertia phase begins since start of the gearshift control. A first hydraulic pressure command (D1) is issued for a predetermined time period. The first hydraulic pressure command (D1) is variable for adjusting the timing of the changeover between the clutches. The second hydraulic pressure command (D2) succeeding the first one is issued until the inertia phase begins. The second hydraulic pressure command is variable for adjusting the torque capacity of the engagement side clutch at the changeover. Thus, the timing of the clutch-to-clutch changeover is appropriately regulated without prolonging a gearshifting time period.
