Shift control apparatus and method for automatic transmission

A shift control apparatus, comprising:

• an automatic transmission in which an engine speed is inputted;
• and
• a shift control section configured to perform a shift change in a shift stage of the automatic transmission to make a gear shift, configured to execute a shift revolution synchronization control in such a manner as to instantaneously release a shift purpose friction element which performs a power transmission through a presently selected shift stage and as to engage another shift purpose friction element which performs the power transmission through a next selection scheduled shift stage in synchronization with the engine speed, and configured to, 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, gradually release an engagement section which performs the power transmission through the presently selected shift stage and gradually engage another engagement section which enables the power transmission through the next selection scheduled shift stage without an execution of the shift revolution synchronization control.
