WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Under certain conditions the transmission will downshift automatically to a lower gear range (without moving the transmission range selector lever). There are four categories of automatic downshifts; Coastdown, Torque Demand, Forced or Kickdown shifts and grade braking.
