ABSTRACT:
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.
