Ford F-650 2015 Owner's Manual page 132

Position 1
• Provides maximum engine braking.
• Allows upshifts by moving gearshift lever.
• The transmission does not downshift into position 1 at high speeds; it
downshifts to a lower gear and then shifts into position 1 when your
vehicle reaches slower speeds.
Forced Downshifts
• Allowed in position D.
• Press the accelerator to the floor.
• Allows transmission to select an appropriate gear.
Allison 2200 with Parking Pawl Feature
Note: Also, see the separate Allison Transmission Operator's Manual.
WARNING: Always set the parking brake fully. Do not use the
gearshift in place of the parking brake.
WARNING: To avoid sudden, unexpected vehicle movement
and possible personal injury or death:
1. Bring the vehicle to a complete stop.
2. Shift the transmission into position P. Slowly lift your foot from the
brake pedal to engage the transmission parking pawl mechanism.
3. Apply the parking brake and make sure it is holding properly. Do not
rely solely on the parking mechanism of the transmission.
4. Turn the engine off when you leave the vehicle. Never leave the
vehicle unattended when the engine is running.
A parking pawl effectively grounds the transmission's output shaft
preventing rotation of the driveline. If your vehicle is stationary, selecting
position P places the transmission in neutral and engages the parking
pawl. Always use the parking brake when parking your vehicle.
Note: If you select position P when your vehicle is moving, the parking
pawl mechanism ratchets and does not hold the truck.
