ABSTRACT:
A control system for an automatic transmission for a vehicle provides an enhancement in a shifting characteristic in a manually shifting mode by controlling an operating hydraulic pressure for hydraulic engage elements in an appropriate manner. In a first range from the output of a shifting command to a time point when a timer TOIPU reaches a counting-up value, or a time point when the slip rate ECL of the hydraulic engage elements exceeds a value YECLIPUS, the operating hydraulic pressure is set at a preset value depending upon the type of shifting. In a second range from the end of the first range to a time point when the timer TOIPU reaches a counting-up value, or a time point when a slip rate ECL exceeds a value TECLIPUS, and in a third range from the end of the second range to a time point when a timer TKAK reaches a counting-up value, the operating hydraulic pressure QAT is set at a value corresponding to an engine torque or a transmission input torque.
