<p>During non-shift modes of transmission operation, the line pressure is controlled according to a first control schedule. Upon a shift being initiated a second control schedule is used. The use of this schedule is maintained until such time as the ratio of the transmission input shaft rotational speed (17) to the transmission output shaft rotational speed (18) reaches a predetermined limit whereafter a third control schedule is utilized. Control is switched from the third control schedule to the first one upon the expiry of a predetermined period which is timed from the point in time a decision that a shift between gears of the transmission should be implemented.</p> |
