A method for controlling a vehicle regenerative braking event includes maintaining a converter clutch closed while braking, while an engine connected to the impeller is running, opening the converter clutch when impeller speed reaches a reference speed difference relative to engine idle speed, and while the engine is off, opening the converter clutch when impeller speed reaches a speed required for a transmission pump, connected to an impeller, to produce line pressure at a desired magnitude.
