ABSTRACT:
A vehicle powertrain including a multiple cylinder internal combustion engine and a controllable transmission controls engine shutdown by shutting off a fuel supply device or devices such as a fuel pump or fuel injector(s) while the transmission is in gear to load the engine and reduce or eliminate engine run-on. The transmission may be controlled to couple the input shaft to a stationary component or simultaneously engage clutches corresponding to different gear ratios to provide a holding torque on the engine.
