ABSTRACT:
An automatic transmission shift control system controls a line pressure for initiating a shift of an automatic transmission so that a duration between initiation of the shift and termination of a torque decline during the shift falls within a predetermined shift initiation time period. Also, a line pressure is controlled by the system for terminating a shift of the automatic transmission so that a duration between termination of a torque decline and termination of the shift falls within a predetermined shift termination time period. Both of the line pressures are used in a following shift control of the automatic transmission.
