ABSTRACT:
A line pressure is adjusted based on data which are updated after evaluation of an inertia phase time of a previous shifting in comparison with a predetermined value. Thus, during the next shifting of the same kind, a shifting friction device is engaged by the line pressure which has been properly adjusted, thus assuring shock-free shifting irrespectively of manufacturing variations and/or degradation with time of component parts.
