ABSTRACT:
A shift control apparatus for an automatic transmission for a vehicle wherein D-N-D in-gear shifts are carried out quickly without any shift shock. Engagement-actuation control for a frictionally engaging element to establish a D range when a shift is made from a N range to the D range comprises a plurality of control stages, for example, an invalid-stroke clearing stage, an intermediate-pressure retaining stage, a feedback stage, etc. When the shift to the D range is made following a shift from the D range to the N range, a shift control apparatus detects the engagement condition of the the frictionally engaging element for establishing the D range, selects one of the control stages in correspondence with the engagement condition, and initiates the engagement-actuation control for the frictionally engaging element from the control stage selected.
