ABSTRACT:
A control system for an automatic transmission employed in a vehicle comprises first and second engaging friction elements provided in the automatic transmission for giving rise to speed change, an operating oil pressure control device for applying operating oil pressure to each of the first and second engaging friction elements in accordance with a predetermined control characteristic so as to change engaging conditions of the first and second engaging friction elements, an information detector for obtaining information of the operating condition of the automatic transmission, and a timing control device for causing the operating oil pressure control device to be operative to adjust a time interval from a time at which the first engaging friction element is changed in its engaging condition to a later time at which the second engaging friction element is changed in its engaging condition in accordance with the information obtained from the information detector, with the information being the revolving speed of a turbine runner provided in a torque converter included in the transmission or information relative thereto, and the temperature of the operating oil or information relative thereto, which affect 2-3 and 3-2 shifts, respectively.
