ABSTRACT:
A shift control system for an automatic transmission including first and second transmission assemblies, which are arranged in tandem to have their shifts controlled individually, and capable of selecting at least two gear stage trains, each being composed of a plurality of gear stages set by combining the first and second transmission assemblies, which are decided under a predetermined condition. It includes a running condition judgment device for judging the present running conditions including the set gear stages; a gear stage train decider for deciding such one of the gear stage trains as is suited for the running conditions; a gear stage train changer for changing one gear stage train to another; a simultaneous shift judgment device for judging if a change from the currently selected gear stage train to another gear stage train produces a simultaneous shift of both the first transmission assembly and the second transmission assembly; and a gear stage train change inhibitor for inhibiting changes of the decided gear stage trains if the simultaneous shifts are judged.
