ABSTRACT:
An automatic transmission control system controls locking pressure for locking a specific friction coupling element to a target level previously determined according to engine output torque and appropriately changes the target level such that, when an increase in engine output torque occurs, a delay of a locking pressure change relative to an engine output torque change becomes greater after the target level has reached near an appropriate level than before it has reached near the appropriate level.
