Abstract

A shift control system for an automatic transmission which can be set both at main gear stages selected on the basis of the running state of a vehicle and at intermediate gear stages having gear ratios intermediate between those of the main gear stages. The shift control system comprises: a running state detector for detecting the running state; a shift decider for deciding a main gear stage to be set, on the basis of the running state detected; a condition decider for deciding whether or not a shift between the main gear stages decided by the shift decider satisfies a predetermined condition; and an intermediate stage setter for deciding an intermediate stage to be set in place of the main gear stage, which was decided by the shift decider, on the basis of the result decided by the condition decider.
