Abstract
A control system for controlling an engine having an automatic transmission includes an engine torque controller for dropping an engine output torque after a downshift signal is provided and calculating a value representative of an engine output torque. The engine output torque is dropped sooner as the value calculated becomes larger when a downshift signal is provided.
