Fully press down the brake pedal.

Move the gearshift lever into the preferred gear.

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

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

The instrument cluster displays the current gear.

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), you can start your vehicle and it 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 the full range of gears.

With the gearshift lever in manual (M), the driver can change gears up or down as preferred. By moving the gearshift lever from drive position drive (D) to manual (M), you now have control of selecting the gear you prefer using buttons on the shift lever.

201

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

The transmission operates through the full range of gears.

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.

E249567

Note: When pressing the button on the gearshift lever, you can cycle through the available drive modes. See Drive Control (page 262).

Your vehicle has a SelectShift Automatic™ transmission gearshift lever. The SelectShift Automatic transmission gives you the ability to change gears up or down without a clutch.

To prevent the engine from running at too low of an RPM, which could cause it to stall, SelectShift will downshift if it determines that you have not downshifted in time.

SelectShift does not upshift, even if the engine is approaching the RPM limit. Shift it manually by pressing the + button.

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

The SelectShift Automatic transmission feature has two modes:

Progressive Range Selection.

Manual (M).

E312894

Progressive Range Selection gives you the ability to lock out gears from the automatic shifting range. This could provide you with an improved driving experience, for example, in slippery conditions or when experiencing a steep slope.

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

202

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

Moving the gearshift lever to the manual

(M) position allows you to manually select the gear you prefer. 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:

203

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.

Chassis Cab Vehicles

Your transmission could reduce the load on the engine when the vehicle stops, and the gear selector is in drive (D) to reduce fuel consumption and emissions. The transmission resumes operation when you release the brake. This feature activates when the transmission is sufficiently warmed, and the vehicle is on a level slope.

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

Your vehicle comes with brake-shift interlock that prevents the gearshift lever from moving from park (P) when you switch the ignition on but have not pressed the brake pedal.

If you cannot move the gearshift lever out of the park (P) position when the ignition is on and the brake pedal pressed, a malfunction could 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 329).

If you do not have a blown fuse 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 - 0, then remove the key. See Starting and Stopping the Engine (page 168).

Move the steering column to the full down and full rearward position, toward the driver seat.

Remove the gearshift lever boot.

204

Place your fingers into the hole where you removed the gearshift lever boot and pull the top half of the 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, then pull straight rearward toward the driver 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.

If your vehicle is stuck in mud or snow, you can 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.

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

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

Note: Use of auxiliary equipment that exceeds the maximum Power Take-Off (PTO) load specified in our 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.

205

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.

Our Super Duty vehicles are approved for use as a stationary, including split shaft capability with 6.7L diesel only, or mobile power source, within limits and operating guidelines detailed in our Truck Body Builders Layout Book. For additional information, visit www.fordbbas.com.
