Abstract
A shift control system for controlling the shifts of a vehicular automatic transmission connected to an engine includes first and second transmission assemblies capable of executing the shifts independently of each other and connected in tandem to each other. The shift control system includes: shift deciding means for deciding that the shifts are to be executed, on the basis of input data; a shift pattern setting element for setting a shift pattern determining a shift point and a gear stage so that the decided shift may be other than the simultaneous one in which the first and second transmission assemblies are simultaneously shifted; and a gear stage determining element for outputting a shift signal so that the shifts may be executed according to the set shift pattern.
