In shift control apparatus and method for an automatic transmission in
which an engine speed is inputted, and a shift change in a shift stage of
the automatic transmission is performed to make a gear shift, a shift
revolution synchronization control in synchronization with the engine
speed is performed and, in a case where the gear shift is made under a
driving state in which there is a possibility of an occurrence of a shift
shock, an engagement section which performs a power transmission under a
presently selected shift stage is gradually released and another
engagement section which enables a power transmission through the next
selection scheduled shift stage is gradually engaged without an execution
of the shift revolution synchronization control.
