ABSTRACT:
A shift control system for an automatic transmission has a multiple stage transmission gear mechanism provided with a plurality of shift gear stages of different speed ratios. A shift control device is provided with a plurality of shift patterns for controlling the multiple stage transmission gear mechanism and establishing one of the shift stages, based on a vehicle operating condition, in light of one of the shift patterns. A shift pattern switch device switches from one shift pattern to the other and back to the one shift pattern from the other when a value representing the vehicle operating condition changes beyond a reference value. A frequency detecting device detects when the frequency of change of the vehicle operating condition goes beyond a predetermined value, and a reference value change device changes the reference value based on the frequency of the change of the vehicle operating condition. The shift control can take into account the driving habits of a driver.
