摘要：
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 temperature of hydraulic oil for the transmission satisfies a predetermined condition. Once the high-temperature shift pattern has been selected, the apparatus inhibits the switching to the high-temperature shift pattern for a predetermined duration, thereby to avoid an excessively frequent hunting between the shift patterns.
