A shift control apparatus for a vehicular automatic transmission provided with
a fuel cut apparatus which cuts off fuel supplied to an engine when an engine speed
exceeds a predetermined value during deceleration of a vehicle, and an automatic
transmission in which a gear shift is achieved with a clutch-to-clutch downshift
in which a hydraulic friction device to be released is released and a hydraulic
friction device to be applied is applied, further includes a controller. The controller
corrects, through learning control, an apply pressure of at least one of the hydraulic
friction devices to be operated for the clutch-to-clutch downshift such that an
amount of drop in a rotational speed of an input shaft of the automatic transmission
decreases when that amount of drop exceeds a predetermined value during the clutch-to-clutch downshift.
