ABSTRACT:
A shift control system for controlling the shifting of a vehicular automatic transmission including a plurality of frictional engagement members and having a plurality of engage/release combinations of the frictional engagement members for setting a predetermined one of gear stages. The shift control system comprises: a changer for effecting a change-over between an automatic shift mode for shifting the automatic transmission automatically on the basis of the running condition of the vehicle and a manual shift mode for shifting the same manually on the basis of the manipulation of the driver; and an engage/release pattern selector for selecting, in the manual shift mode, an engage/release combination of the frictional engagement members, which is different from the combination selected in the automatic shift mode, as that for setting the predetermined gear stage.
