ABSTRACT:
A shift control apparatus for an automatic transmission provides a normal-temperature shift pattern and a high-temperature shift pattern. The high-temperature shift pattern is selected when a transmission fluid temperature satisfies a predetermined condition. The switching of the shift pattern is inhibited if the vehicle speed is lower than a predetermined speed, even when the temperature related to the transmission or engine has been judged to be higher than a predetermined temperature.
