Abstract
A method and system provides a Neutral Hold mode in a vehicle having a shift-by-wire transmission with a return to park feature. The Neutral Hold mode is entered upon detecting when the transmission control mechanism has been used a first time to select Neutral when a driver's door is open or has been used a second time to select Neutral. When in Neutral Hold mode, the transmission will stay in Neutral and not shift to Park upon detecting that a driver has exited the vehicle.
