•DEF freezes below 12°F (-11°C). Your vehicle is equipped with an
automatic pre-heating system which allows the DEF system to
operate below 12°F (-11°C).
•Do not store the DEF bottle in your vehicle. If it leaks, it could cause
damage to interior components or release an ammonia odor inside
your vehicle.
•Store DEF out of direct sunlight and in temperatures between
23°F–68°F (-5°C–20°C).
NOISE EMISSIONS
In order to keep to the federal exterior noise regulations, your vehicle
may be equipped with noise emission items. Depending on your vehicle
configuration, it may have all or some of the following items:
Air Intake System:Inspect the air cleaner. Do not alter its location. Do
not alter inlet and outlet piping.
Body:Inspect wheel well splash shields, cab shields and under hood
insulation for deterioration, dislocation and orientation.
Cooling System:
•Inspect the fan for blade damage. If you find any damage, replace
with the recommended parts. Inspect for fan-to-shroud interference
and any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers damp-out engine mechanical
noise. If they need replacing, make sure to replace them with the
recommended parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•
Perform a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended replacement parts.
•Do not change the tail pipe elbow or offset tail pipe orientation from the
standard position as originally received.

MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
You can see the manual transmission shift patterns on either the shift
lever knob or the sun visor. Study this information carefully before you
drive your vehicle even though you may be familiar with similar units. Do
not attempt to drive your vehicle without knowing the exact shift pattern
of the transmission. Consult an authorized dealer if any questions exist
as to the shifting instructions posted in your vehicle.
Driving Hints
WARNING:Do not coast the vehicle with the clutch pedal
pressed or with the transmission in neutral. This practice could
result in loss of vehicle control.
The following driving hints are a brief, general guide in operating the
different manual transmissions used in your vehicle.
•When shifting into first gear or reverse with your vehicle standing
still, quickly release and press the clutch pedal (if necessary to
complete gear engagement).
•Always use the lowest (or most appropriate) gear to start your
vehicle.
•Always use a gear ratio low enough to allow the engine to operate
above the minimum engine operation speed range.
•Do not lug the engine.
•Do not slam or jerk the gearshift lever into gear.
•When more power is required, shift to a lower gear and accelerate
the engine near the governed speed.
To go forward, press the clutch pedal in and shift into first gear while
the engine is idling. Engage the clutch while pressing the accelerator to
start forward. Operate the clutch and upshift as required by driving
conditions.
To go backward, put the gearshift lever in reverse and engaging the
clutch while pressing lightly on the accelerator.
Shifting with a Synchronized Transmission
With the clutch pedal pressed in, use the second gear synchronizer to
stop the clutch disc rotation, this allows smooth engagement of first gear
or reverse. To complete the gear engagement, it may be necessary to
apply light pressure to the gearshift lever during initial engagement of
the clutch. It takes a second or two to match gear speeds; steady
pressure on the gearshift lever helps the synchronizer perform its job
122Transmission

more quickly. If you force the gearshift lever into position, this action
defeats the purpose of the synchronizer by causing gear clash.
Shifting with a Non-Synchronized Transmission
SeeClutch brakeandDouble clutch proceduresin theClutchsection
of this chapter.
Clutch
Do not ride or slip the clutch as this causes unnecessary heat and wear.
Maintain the specified clutch adjustment to prolong its life and regularly
inspect the clutch control linkage for tightness. See theScheduled
Maintenancechapter for other maintenance information. When
adjustment of the clutch is necessary, it is very important that the work
be performed properly or early clutch failure may result and a costly
clutch overhaul may become necessary. Only a qualified technician
should perform clutch work.
Note:Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a failure of the
engine, transmission or clutch components.
Note:To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold your vehicle at a
standstill on an upgrade as when waiting for a traffic light.
Engaging the Clutch
•Always start in the proper gear. An empty vehicle can start in a
higher gear than a fully loaded vehicle. Starting in too high a gear can
cause clutch slippage and excessive heat and wear on the clutch. A
gear that starts the vehicle moving at idle speed is the correct gear. If
you have to rev the engine to get your vehicle going, the gear
selection is too high.
•Do not shift until your vehicle has reached the proper speed.
Upshifting before your vehicle has reached the proper speed can
cause clutch slippage and excessive heat and wear on the clutch.
•Never hold a vehicle on a grade with the clutch. This causes the
clutch to slip and can actually burn up the clutch.
•Never coast with the clutch disengaged. The high RPM (sometimes
over 10000) can actually burst the facing material of the clutch.
•Never engage the clutch while coasting. Re-engaging the clutch after
coasting may not only cause a great shock to the clutch, but the
whole drivetrain. Internal engine damage or clutch and flywheel
failure can result from this.

If the transmission is equipped with a ceramic clutch, you must start
your vehicle moving in first gear and engage the clutch before pressing
the accelerator at idle. In addition, do not try to slip the clutch by raising
engine RPM and riding or feathering the clutch pedal since this causes
erratic engagement that can cause engine stalling and potential serious
damage to driveline components.
Clutch Brake (Non-Synchronized Transmissions) - Vehicle
Stationary
A clutch brake stops transmission input shaft rotation so you can
accomplish the initial first gear or reverse gear selection when your
vehicle is stationary and the engine is at idle speed. Clutch brake
application occurs in the last 1 inch (25 millimeters) of clutch pedal
travel.
When using the clutch brake, fully press the clutch pedal and shift the
transmission into first gear or reverse. If the transmission does not go
into one of these gears, slowly release the clutch pedal while applying
light pressure on the transmission shift lever until it shifts into gear.
Note:After engagement of first gear, do not use the clutch brake for
upshifting or downshifting. If you do, clutch brake life shortens and gear
selection shift efforts may increase.
Double-Clutch Procedures - Non-Synchronized Transmissions
In order to properly upshift or downshift:
1. Press the clutch pedal to disengage the clutch.
2. Shift the transmission into neutral.
3. Release the clutch pedal.
If upshifting, wait until the engine speed matches the transmission speed
of the gear you are selecting.
If downshifting, accelerate the engine until the engine speed matches the
input speed of the gear you are selecting. Press the clutch pedal
immediately and shift into the desired gear, then release the clutch
pedal.

Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents you from moving the gearshift lever from position
Pwhen the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of positionPwith the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or your vehicle’s brake lamps are not operating properly. See
theFuseschapter.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

Allison 2200 with Parking Pawl Feature
Note:Also, see the separateAllison 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 positionP.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
positionPplaces the transmission in neutral and engages the parking
pawl. Always use the parking brake when parking your vehicle.
Note:If you select positionPwhen your vehicle is moving, the parking
pawl mechanism ratchets and does not hold the truck.

Allison 3000
Note:For more information about this transmission, see the separate
Allison 3000 Series Operator’s Manual.
The Allison 3000 series offers two shift modes: Performance and
Economy.
Performance mode gives the best all-around transmission operation. The
transmission defaults to this mode when you start the engine. Pressing
MODE on the shifter switches to Economy mode and illuminates the
Mode ON lamp.
Economy mode provides operation at lower engine RPM while
maintaining adequate performance.
If the engine speed is above idle when a gear is selected using the
shifter, the vehicle does not move; the shifter must be moved to re-select
a gear after the engine speed returns to idle.
Torque Lock
If you park your vehicle on an incline without properly engaging position
P(by shifting into positionPbefore applying the parking brake), the
weight of the vehicle may generate an excessive amount of torque on the
parking pawl. This makes it difficult to shift the transmission out of
positionP.Hold the brake pedal down while shifting out of positionP,
then release the parking brake.
