A shift control system for an automatic power transmission incorporates a storage means, responsive to an entered shifting demand, for temporarily storing instantaneous preselected shift control parameter data relative to the entered shifting demand. The control system also includes means for detecting the vehicular driving condition where no shifting demand may occur, for updating driving pattern data which is used for recollection of a driving pattern corresponding to or approximately corresponding to one of a shifting pattern or a schedule so that updating of the driving pattern data may not interfere with recollection of the driving pattern to enable appropriate selection of the transmission speed ratio at any vehicle driving condition.
