ABSTRACT:
A shift control system for obtaining a smooth shift feeling in a shifting necessitating redeployment of friction elements. The shift control system is comprised of a sensor which detects a state that disengagement pressure of a friction element to be disengaged almost becomes zero during shifting. In reply to the detection of the sensor, a controller adjusts engagement pressure of the other friction element to be engaged at a predetermined value determined according to input torque and gear ratio.
