PROBLEM TO BE SOLVED: To prevent the deterioration of a drivability by finishing a shift in an early time, even if the torque transmission capacity of a hydraulic connection element is reduced and the shift is not advanced on the way, in a device by which the oil pressure (connection pressure) of a connection side hydraulic connection element is changed in a lower oil pressure range than a line pressure at the shift time and the connection pressure is boosted to the line pressure, after the input/output speed ratio Gratio of a transmission is settled in a prescribed range which is the judging standard of a shift completion. SOLUTION: An elapsed time (TMSTB-TM) since a connection pressure increases to a prescribed pressure QUPONB is measured and even if a Gratio is not settled in a prescribed range (between YG(N+1)L and YG(N+1)H) which is the judging standard of the shift completion, when TMSTB-TM reaches a prescribed time YTMUP4 (S32), a shift completion treatment is carried out (S11) and the connection pressure is boosted to a line pressure. |
