Transmission Operation - Ford 2013 F-650 Owner's Manual

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
WARNING: Hold the brake pedal down while you move the
gearshift lever between positions. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and cause property
damage, personal injury or death.
Main transmission, auxiliary transmission, transfer case and power
take-off (PTO) control shift patterns can be found on a placard or decal
on the driver's sun visor, on the instrument panel or on the shift control
itself.
The main transmission control is used to select the various gear ratios or
speeds of the transmission. Selecting position D does not change the
transmission gear ratio, but is used where the gear ratios in the main
transmission are adequate to handle the vehicle operation.
If the transmission fails to shift properly, check the inline 10A fuse
located in the battery cables above the battery.
Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents the gearshift lever from being moved from position
P when the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of position P with the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or the vehicle's brake lamps are not operating properly. See
the Fuses chapter.
WARNING: Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING: When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
