To prevent the engine from running at toolow an RPM, which could cause it to stall,SelectShift still makes some downshiftsif it has determined that you have notdownshifted in time. Although SelectShiftmakes some downshifts for you, it stillallows you to downshift at any time if theSelectShift determines that there is nodamage to the engine from over-revving.
SelectShift does not automatically upshift,even if the engine is approaching the RPMlimit. Shift manually by pressing the (+)button.
Note:Engine damage could occur if you revthe engine excessively and hold it withoutshifting.
Progressive Range Selection (If
Equipped)
Progressive range selection gives you theability to lockout gears from the automaticshifting range. This could provide you withan improved driving experience, forexample, in slippery conditions or whenexperiencing a steep slope.
With the gearshift lever in drive (D), pressthe (–) button to activate progressiverange selection. The instrument clusterindicates the available and selected gears.
All available gears display with the currentgear indicated. Press the (–) button againto lock out gears beginning with the highestgear. For example, press the (–) buttontwice to lock out 6th and 5th gears. Onlythe available gears display, and thetransmission shifts between the availablegears. Press the (+) button to unlock gearsto allow the transmission to shift to highergears. The transmission shifts within thegear range you select.

Automatic Transmission AdaptiveLearning
This feature could increase durability andprovide consistent shift feel over the lifeof your vehicle. A new vehicle ortransmission may have firm shifts, softshifts, or both. This is normal and does notaffect the function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation.
Brake-Shift Interlock
WARNING: Do not drive yourvehicle until you verify that thestoplamps are working.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) whichmeans your vehicle can roll freely. Toavoid unwanted vehicle movement,apply the parking brake prior to doingthis procedure. Use wheel chocks ifappropriate.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Your vehicle has a brake-shift interlockfeature that prevents the gearshift leverfrom moving from park (P) when youswitch the ignition on but have not pressedthe brake pedal.
If you cannot move the gearshift lever outof the park (P) position with the ignition inthe on position and the brake pedalpressed, a malfunction could haveoccurred. It is possible that a fuse hasblown, or your vehicle’s brake lamps arenot operating properly. See FuseSpecification Chart (page 202).
If you do not have a blown fuse and thebrake lamps are working properly, thefollowing procedure allows you to movethe gearshift lever from park (P):
1.Apply the parking brake. Switch theignition key to off, then remove the key.
2.Move the steering column to the fulldown and full rearward position,toward the driver seat.
3.Remove the gearshift lever boot.
4.Place your fingers into the hole whereyou removed the gearshift lever bootand pull the top half of the shroud upand forward to separate it from thelower half of the shroud. There is ahinge at the forward edge of the top ofthe shroud. Roll the top half of theshroud upward on the hinge point, thenpull straight rearward toward the driverseat to remove.
5.Remove the top half of the shroud.
6.Remove the three fasteners under thecolumn that secure the lower shroudhalf to the column.
7.Pull the lock lever into the full unlockedposition and remove the lower shroudcover by pulling the lever handlethrough the slot in the cover.
8.Apply the brake. Gently lift the overridedisk and move the gearshift lever intoneutral (N).

9.Start your vehicle.
Perform Steps 4 through 8 in reverse order,making sure to engage the hinge pivotsbetween the upper and lower halves of theshroud. Keep slight pressure in the forwarddirection as you rotate the halves together.
If Your Vehicle Gets Stuck in Mudor Snow
Note:Do not rock your vehicle if the engineis not at normal operating temperature ordamage to the transmission could occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires could occur, or theengine could overheat.
If your vehicle is stuck in mud or snow, youcould rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
POWER TAKE-OFF (IF EQUIPPED)
Auxiliary equipment called power take-off,or PTO, is often added to the engine ortransmission to operate utility equipment.Examples include a wheel-lift for towtrucks, cranes, tools for construction or tireservice and pumping fluids. PTOapplications draw auxiliary horsepowerfrom the powertrain, often while the
vehicle is stationary or mobile. In thestationary condition, there is limitedcooling air flow through the radiator andaround the vehicle that normally occurswhen a vehicle is moving. The aftermarketPTO system installer, having the mostknowledge of the final application, isresponsible for determining whetheradditional chassis heat protection orpowertrain cooling is required and alertingthe user to the safe and proper operation.
Your vehicle is approved for use as aStationary Mode, SplitShaft Mode orMobile Mode power source within the limitsand operating guidelines detailed in theFord Truck Body Builders Layout Book,found at https://fordbbas.com/home andthrough the Ford Truck Body BuildersAdvisory Service. The transmission powersource modes are engine specific.

GENERAL INFORMATION
WARNING: Exceeding these ratingsby overloading can cause componentfailure resulting in property damage,personal injury or death.
Fluid Temperature
If the operating temperature exceeds250°F (121°C), the rate of axle lubricationoxidation increases and shortens the lifeof the lubricant and seals, requiring axlelubrication changes to become morefrequent to preserve the axle. Do notconsistently run extreme pressure (EP)lubricants above 250°F (121°C).
Axle Conversions
WARNING: When operating aloaded vehicle, the driver must keep alladjustable axles on the ground at alltimes, supporting their share of thevehicle’s load. Failure to do so canoverload other axles, tires, wheels,springs, steering components, brakesand frames, resulting in early componentfailure, loss of vehicle control, possibleproperty damage and personal injury.
We do not recommend, or approve,performing axle conversions. However, weunderstand that, on occasion, others installaftermarket add-on axles on the truckchassis that allow operator control forweight transfer from other axles (such asair lift axles).
2-SPEED REAR AXLE (IF EQUIPPED)
WARNING: Never shift atwo-speed axle when descending asteep grade as this may cause loss ofvehicle control and result in personalinjury.
Note:Do not shift between ranges whenthe speed control is on.
A two-speed rear axle allows the driver toselect a low range for greater pulling powerand a high range for greater road speedand fuel economy. You can also use theseranges to provide extra steps betweentransmission shifts when driving on steepgrades or fuel economy may be factors.
Axle Shifting
Note:Do not shift the axle to LOW whenyour vehicle is moving. Use LOW when youdrive a fully loaded vehicle on a severe gradeor in congested traffic. Use HIGH for allnormal driving conditions with a lightlyloaded or partially loaded vehicle.
Note:The axle is set to HIGH by default.
To shift the axle between HIGH and LOWwith the vehicle stopped, place thetransmission in position N, then press andhold the button for two seconds.

WHAT IS THE PNEUMATIC
LOCKING DIFFERENTIAL
The pneumatic locking differential can lockor unlock the differential when the vehicleis moving or stopped. The differential lockprovides full power to both wheels whenextra traction is required.
HOW DOES THE PNEUMATIC
LOCKING DIFFERENTIAL
WORK
If your vehicle is equipped with apneumatic locking differential:
•Power is transmitted to the oppositewheel should one of the wheels beginto slip.
•Raise both wheels off the ground if itbecomes necessary to operate onewheel with the vehicle stationary.
The differential can be locked or unlockedwhen the vehicle is moving at a constantspeed of less than 25 mph (40 km/h) andwhile the wheels are not slipping. Do notlock the differential when the vehicle istraveling down steep grades and tractionis minimal.
Note:Do not use the differential lock atvehicle speeds above 25 mph (40 km/h).
When the differential is locked, thevehicle’s turning radius increases causingundersteer.
The differential lock and differential locklight automatically disengage at speedsabove 25 mph (40 km/h). The differentiallock remains off until the vehicle isrestarted or the differential lock switch isturned off then back on.
PNEUMATIC LOCKING
DIFFERENTIAL PRECAUTIONS
WARNING: Exceeding any vehicleweight rating can adversely affect theperformance and handling of yourvehicle, cause vehicle damage and canresult in the loss of control of yourvehicle, serious personal injury or death.
WARNING: Failure to raise all drivewheels with this type of differential couldcause the vehicle to move unexpectedly,resulting in property damage, personalinjury or death.
WARNING: Sudden accelerationon slippery surfaces could cause thewheels to spin, the vehicle to turnsideways on a crowned road surface orin a turn, possibly resulting in loss ofvehicle control and personal injury.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked as soon as possible. If thevehicle has continuous vibration or shudderin the steering wheel while braking, have thesystem checked as soon as possible.
All standard equipment brakes areself-adjusting. Automatic adjustment,when required, occurs whenever you applyand release the brakes during forward orreverse operation.
Know the required stopping distances forall driving conditions you may encounter.For longer brake lining life, take fulladvantage of engine braking power whencoming to a stop.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
If the brakes do not grip well:
•Check brake adjustment.
•Check the brake linings for excessivewear.
•Check the system air pressure onvehicles with air brakes.
•Let the brakes cool if you have beenusing them excessively, as in mountaindriving or after several fast, high-speedstops.
•If you have been driving through deepwater, gently apply the brakes severaltimes while your vehicle is movingslowly.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If the light does not illuminateduring start up, remains on orflashes, the system may bedisabled. It also momentarily illuminateswhen you switch the ignition on to confirmthe lamp is functional. If it does notilluminate when you switch the ignition on,or begins to flash at any time, have thesystem checked.
If you connect a PLC trailer withthe ignition on, the trailer ABSlight also illuminates. If the lightfails to illuminate, if it remains on after youstart the vehicle or continues to flash, havethe system serviced immediately.
See Warning Lamps and Indicators(page 67).

If the system is disabled, normalbraking is still effective. If thebrake warning lamp illuminateswith the parking brake released, have thesystem checked immediately. It alsomomentarily illuminates when you switchthe ignition on to confirm the lamp isfunctional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the systemchecked.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.
PARKING BRAKE
Hydraulic Brakes (If Equipped)
WARNING: Always set the parkingbrake and leave your vehicle with thetransmission in park (P).
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Apply the parking brake whenever thevehicle is parked. To set the parking brake,pull the handle up until it snaps into thelocked position.
When the parking brake is out ofadjustment, seek service immediately.
The parking brake warning lampin the instrument clusterilluminates, and remainsilluminated (when you switch on theignition), until you release the parkingbrake.
