Patent ID: 7384358

Claim:
An automatic transmission control apparatus, which controls engagement and disengagement of each corresponding one of a plurality of friction arrangements of an automatic transmission of a vehicle by controlling application of a fluid pressure of operating fluid to a corresponding one of a plurality of drive pistons, which are assigned to and drive the plurality of friction arrangements, respectively, the automatic transmission control apparatus comprising: a selecting means for selecting each corresponding one of the plurality of friction arrangements, which is driven in an engaging direction to achieve the engagement at time of next gear shift to transmit torque, as a standby friction arrangement that is placed in a standby state for implementing the next gear shift; and an applying means for applying a standby fluid pressure to each corresponding one of the plurality of drive pistons, which drives the corresponding standby friction arrangement, before the next gear shift, wherein the standby fluid pressure is for sliding each corresponding one of the plurality of drive pistons, which drives the corresponding standby friction arrangement, within a range that does not cause transmission of the torque through the corresponding standby friction arrangement.
