Ford Super Duty (2018 year). Manual — part 52

First (1)

•

Transmission operates in first (1) gear
only.

•

Provides maximum engine braking.

•

Allows upshifts by moving gearshift
lever.

•

Does not downshift into first (1) gear
at high speeds; allows for first (1) gear
when vehicle reaches slower speeds.

Forced downshifts

•

Allowed in drive (D) with the tow/haul
feature on or off.

•

Press the accelerator to the floor.

•

Allows transmission to select an
appropriate gear.

Tow/Haul Mode

WARNING

Do not use tow/haul when the road
surface is slippery. Failure to follow
this instruction could result in the

loss of control of your vehicle.

E161509

To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator

light illuminates in the instrument cluster.

The tow/haul feature:
•

Delays upshifts to reduce the frequency
of transmission shifting.

•

Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.

•

Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided varies
based upon the amount you press the
brake pedal.

The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.

Note: If your vehicle is equipped with the
Adaptive Steering System, enabling the
tow/haul feature adjusts the steering
response. In tow/haul mode the Adaptive
Steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds
when maintaining the ease of parking and
maneuverability at low speeds. See
Steering (page 261).

To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever when
tow/haul is active. The TOW HAUL light
deactivates. Tow/haul also deactivates
when you power down your vehicle.

Understanding your SelectShift
Automatic™ transmission

(If Equipped)

E163184

Your vehicle is equipped with a SelectShift
Automatic™ transmission gearshift lever.
The SelectShift Automatic transmission
gives you the ability to change gears up or
down (without a clutch) as desired.

In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically make
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.

SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the + button.

Note: Engine damage may occur if you
maintain excessive engine revving without
shifting.

The SelectShift Automatic transmission
feature has two modes: PRS and M mode.

PRS (Progressive Range Selection)

Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with
an improved driving experience (for
example, in slippery conditions or when
experiencing a steep grade).

With the gearshift lever in drive (D), press
the – button to active PRS. The available
and selected gears are indicated on the
instrument cluster.

All available gears display with the current
gear indicated. Press the – button again to
lock out gears beginning with the highest
gear. Example: press the – button twice to
lock out 6th and 5th gears. Only the
available gears display and the
transmission automatically shifts between
the available gears. Press the + button to
unlock gears to allow the transmission to
shift to higher gears. The transmission
shifts automatically within the gear range
you select.

Manual (M)

Moving the gearshift lever to the manual
(M) position allows you to manually select
the gear you desire. Only the current gear
displays. Use the buttons on the gearshift
lever to manually select gears. Press the
+ button to upshift or the – button to
downshift. Return the transmission to a
different gearshift position to deactivate
manual control.

Automatic Transmission Adaptive
Learning

This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.

Brake-Shift Interlock

WARNINGS

When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can

roll freely. To avoid unwanted vehicle
movement, always fully apply the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate.

If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be

working properly. Have your vehicle
checked as soon as possible.

Note: Do not drive your vehicle until you
verify that the brake lamps are working.

Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is on and the brake pedal
is not pressed.

If you cannot move the gearshift lever out
of park (P) position with the ignition is on
and the brake pedal pressed, a malfunction
may have occurred. It is possible that a
fuse has blown or your vehicle’s brake
lamps are not operating properly. See
Fuse Specification Chart (page 318).

If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):

1.

Apply the parking brake. Switch the
ignition key to 1 (off), then remove the
key.

2. Move the steering column to the full

down and full rearward position
(toward the driver’s seat).

3. Remove the gearshift lever boot.

4. Place fingers into hole where you

removed the gearshift lever boot and
pull top half of shroud up and forward
to separate it from the lower half of the
shroud. There is a hinge at the forward
edge of the top shroud. Roll the top
half of the shroud upward on the hinge
point to clear the hazard flasher button,
then pull straight rearward toward the
driver’s seat to remove.

5. Remove the top half of the shroud.

6. Remove the three fasteners under the

column that secure the lower shroud
half to the column.

E163185

7.

Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover.

8. Apply the brake. Gently lift the override

disk and move the gearshift lever into
neutral (N).

E163186

9. Start your vehicle.

Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as you rotate the halves together.

If Your Vehicle Gets Stuck In Mud
or Snow

Note: Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.

Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires may occur, or the
engine may overheat.

If your vehicle is stuck in mud or snow, you
may rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear.
