ABSTRACT:
A shift control apparatus for an automatic transmission includes a pre-shift device that operates a predetermined synchromesh, based on a prediction by a predicting device. It thereby couples together a transmission input shaft (with a friction transfer mechanism that has not been used to effect a current gear position) and a transmission output shaft, through a predetermined gear train, and brings them into a standby state. The time when it is determined that the friction transfer mechanism that has not been used to effect of the current gear position has been disengaged is taken as the timing with which the synchromesh coupling operation by the standby control is started, regardless of the completion of the achievement of the current gear position.
