Abstract
A vehicle having an automatic transmission includes a roll-back detector that generates a roll-back signal indicating a vehicle roll-back event. A controller receives the roll-back signal and determines whether the automatic transmission is in a forward drive mode having first and second torque transfer elements engaged. The controller engages a third torque transfer element to prevent the vehicle roll-back event.
