Abstract
A vehicle includes an engine and a transmission having an input shaft operably coupled to the engine, an output shaft operably coupled to wheels of the vehicle, a primary pump, and a secondary pump. The primary and secondary pumps are each configured to supply pressurized fluid to a valve body of the transmission. A controller is programmed to, in response to a loss of pressure of the primary pump and a speed of the output shaft exceeding a first threshold, shift the transmission to a neutral state, energize the secondary pump once the transmission is in the neutral state, and command the engine to idle speed.
