2018 Ford F-350 Owners Manual - Transmission

Transmission

Always fully apply the parking brake. Make sure you shift into park (P) for vehicles with an automatic

transmission. Switch the ignition off and remove the key whenever you leave your vehicle.

When your vehicle is stationary, keep the brake pedal fully pressed when shifting gears. Failure to follow this

instruction could result in personal injury, death or property damage.

Note: You may not be able to shift out of park (P) unless the intelligent access key is inside your vehicle.

(If Equipped)

E163183

Fully press down the brake pedal.

Move the gearshift lever into the desired gear.

When you are finished driving, come to a complete stop.

Move the gearshift lever and securely latch it in park (P).

This position locks the transmission and prevents the rear wheels from turning.

With the gearshift lever in reverse (R), your vehicle moves backward. Always come to a complete stop before shifting into and out of reverse (R).

With the gearshift lever in neutral (N), your vehicle can be started and is free to roll. Hold the brake pedal down when in this position.

Drive (D) is the normal driving position for the best fuel economy. The drive function allows automatic upshifts and downshifts through gears one through six.

With the gearshift lever in manual (M), the driver can change gears up or down as desired. By moving the gearshift lever from drive position drive (D) to manual (M) you now have control of selecting the gear you desire using buttons on the shift lever. See Understanding your SelectShift Automatic™ transmission later in this section.

To return to normal drive (D) position, move the shift lever back from manual (M) to drive (D).

The transmission operates in gears one through six.

Transmission operates in second (2) gear only. Use second (2) gear to start-up on slippery roads.

208

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.

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.

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.

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 259).

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.

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.

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.

Moving the gearshift lever to the manual

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.

Upshift according to the following chart:

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.

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 317).

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):

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

Move the steering column to the full down and full rearward position (toward the driver’s seat).

Remove the gearshift lever boot.

211

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.

Remove the top half of the shroud.

Remove the three fasteners under the column that secure the lower shroud half to the column.

E163185

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.

Apply the brake. Gently lift the override disk and move the gearshift lever into neutral (N).

E163186

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.

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.

Use of auxiliary equipment that exceeds the maximum Power

Take-Off (PTO) load specified in the Ford Truck Body Builders Layout Book can adversely affect the performance of the powertrain system. Refer to the Body Builders Layout Book for instructions about the appropriate installation of additional equipment.

Auxiliary equipment called power take-off, or PTO, is often added to the engine or transmission to operate utility equipment. Examples include a wheel-lift for tow trucks, cranes, tools for construction or tire service, and pumping fluids. PTO applications draw auxiliary horsepower from the powertrain, often while the vehicle is stationary. In this condition, there is limited cooling air flow through the radiator and around the vehicle that normally occurs when a vehicle is moving. The aftermarket PTO system installer, having the most knowledge of the final application, is responsible for determining whether additional chassis heat protection or powertrain cooling is required, and alerting the user to the safe and proper operation.

Ford Super Duty Vehicles are approved for use as a stationary (including split shaft capability) or mobile power source, within limits and operating guidelines detailed in the Ford Truck Body Builders Layout Book, found at www.fleet.ford.com/truckbbas, and through the Ford Truck Body Builders Advisory Service.
