Torque Demand
WARNING: This page is about a different car, the 2011 Lincoln MKZ and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The torque demand downshift occurs (automatically) during part throttle acceleration when the demand for torque is greater than the engine can provide at that gear ratio. If applied, the transaxle will disengage the Torque Converter Clutch (TCC) to provide added acceleration.
