Abstract
A control system for a power train of an automotive vehicle prevents thermally overloaded state of a hydraulically controlled automatic transmission when a severe thermal load condition of an engine is maintained for a predetermined time. An engine controller is supplied with signals representing a throttle opening, an engine speed and a vehicle speed, and performs an engine torque reduction control when the transmission has been judged to be under a thermally overloaded condition, so as to prompt a driver to effect a downshifting and thereby eliminate an overloaded state of the transmission.
