Contaminated DEF
SCR systems are sensitive to contamination of the DEF. USE ONLY
CERTIFIED DIESEL EXHAUST FLUID. If the system becomes
contaminated and you continue to drive your vehicle with contaminated
DEF, the following warnings result:

If any of these warnings appear, you must purge the contaminated DEF
and replace it with approved DEF. See an authorized dealer or the
Workshop Manual.
Upon filling the DEF tank after a DEF contaminated warning, normal
operation resumes when you restart your vehicle.
DEF Guidelines and Information
•DEF is non-flammable, non-toxic, colorless and water-soluble.
•Use only DEF that carries the trademark: AMERICAN PETROLEUM
INSTITUTE CERTIFIED DIESEL EXHAUST FLUID.
•An ammonia odor may be smelled when the cap is removed or during
a refill. Refill the DEF tank in a well-ventilated area.
•Before filling the tank, make sure the surrounding area is clean of
debris to prevent contamination.
•Do not dilute DEF with water or any other liquid.
•Do not put DEF in the fuel tank or any other tank on your vehicle.
•Do not re-use the nozzle or the DEF container once it is empty.
•Do not overfill the DEF tank.
•Avoid spilling DEF on painted surfaces, carpeting or plastic
components. Immediately wipe away any DEF that has spilled on
painted surfaces with a damp cloth and water. If it has already
crystallized, use warm water and a sponge.

Allison 2500
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 positionN.
3. Apply the parking brake and make sure it is holding properly.
4. Turn the engine off when you leave the vehicle.Never leave the
vehicle unattended when the engine is running.
This transmission is available with a column-mounted gearshift lever. The
instrument cluster displays the gear positions.
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.

the gear teeth. This may damage the PTO unit and the transmission PTO
drive gear teeth, resulting in further damage to the transmission and
PTO.
PTO Operation with Vehicle Stationary
WARNING:When the PTO is operated with the vehicle
stationary, the transmission must be placed in positionNwith the
parking brake set. If the transmission is not in positionNand is
equipped with a remote throttle control, an increase in engine speed
can overpower the parking brake and cause the vehicle to move,
possibly resulting in personal injury and/or property damage.
Stop your vehicle, idle the engine and set the parking brake. Make sure
the gear selector is in any forward drive range, and then engage the
PTO. After engaging the PTO, move the range selector to positionN.
Increase the engine speed until reaching the desired PTO operation
speed. To disengage the PTO after operation with your vehicle standing,
release the throttle, allow the drive equipment to come to a stop, and
then disengage the PTO.
PTO Operation while Vehicle Is Moving
After engaging the PTO for driven vehicle operation, shift to the desired
range and drive your vehicle. The speed of the PTO, during this period
of operation, always maintains direct relation to vehicle speed. PTO
speed decreases in relation to vehicle (transmission output) speed as
shifts to a higher gear occur. When operating the PTO while your vehicle
is moving, the PTO may be disengaged whenever it is no longer required.
When there is no load on the PTO gear, you can pull it out of
engagement.
Vehicles Equipped with an Allison 3000 Series Automatic
Transmission
The PTO drive gear is engine-driven and provides direct engine power.
You can operate the PTO when your vehicle is either stationary or
moving. The PTO gear is in constant mesh with the drive gear in the
torque converter housing. A friction clutch or constant drive transmits
power to the PTO.
Vehicles Equipped with a Manual Transmission
Transmission-mounted PTO units are available for local installation on
your vehicle. See yourBody Builder’s Layout Bookfor restrictions on
use and installation of PTO units.

To shift the axle from LOW to HIGH with your vehicle stopped, place the
transmission in positionN,then press the lower part of the switch.
To shift the axle from LOW to HIGH with your vehicle moving, accelerate
to approximately 35 mph (56 km/h), press the lower part of the switch
while the transmission is in positionN,then release and apply the
accelerator.
To shift the axle from HIGH to LOW with the vehicle stopped, place the
transmission in positionN,then press the upper part of the switch.
Split-shifting (Combined Axle and Transmission Shift) (Manual
Transmission Only)
To downshift the axle to a slower ratio and shift the transmission, shift
the transmission and move the switch to the lower ratio before the
clutch is re-engaged.
To upshift the axle and shift the transmission, move the switch to a
faster ratio and make the transmission shift in the usual manner.

Ratio Extender Use
Low end:You can use a two-speed axle as a ratio-extender when
split-shifting is not necessary. For low end use, just shift the axle into
LOW to start out, and shift to HIGH when you longer need the extra
torque.

the system with air from an outside source, releasing the spring-actuated
parking brakes. Your vehicle is now ready to tow in an emergency.
You can only use an outside air source if the protected system is in
operating condition. If you cannot restore air pressure in the protected
air system, you must release the spring-actuated brakes manually.
Releasing Spring Manually
WARNING:Do not attempt to disassemble the parking brake
chamber under any circumstances. The high spring load may
cause serious injury if the chamber clamps are removed.
If you release air pressure from the spring brake chamber, the power
spring applies the brake and, unless air pressure can be re-established,
you must release the spring brake as follows in order to move your
vehicle.
WARNING:Block the wheels to help prevent the vehicle from
moving.
WARNING:Unexpected and possibly sudden vehicle movement
may occur if these precautions are not taken.
Do not use impact wrenches as they may damage the piston and prevent
proper caging of the spring. Do not apply more than 50 foot-pounds
(68 newton-meters) torque to the release bolt nut.
1. Remove the stud tool and nut
from the carrying pocket on the
brake chamber assembly.
2. Remove the access plug from the
end of the spring chamber.
3. Insert the release stud through
the opening in the chamber and
into the spring pressure plate.

Installing the Axle Shafts
1. Remove the covers from the wheel ends.
2. Shift the differential lock to the unlocked (disengaged) position.
3. Install the axle shafts.
•Place the gaskets on the wheel hub studs.
•Push the right-hand axle shaft and gasket into the wheel end and
housing until the shaft stops against the differential shift collar.
•Push down and in on the axle shaft flange and rotate the shaft
until the splines of the shaft and shift collar are engaged.
•Push the axle shaft further into the housing until the shaft stops
against the differential side gear.
•Push down on the axle shaft flange and rotate the shaft until the
splines of the shaft and side gear engage.
•Push the axle shaft completely into the housing until the axle
shaft flange and the gasket are flush against the wheel hub.
•Install the left-hand axle shaft and gasket into the wheel end.
4. If tapered dowels are required, install them at each stud and into the
flange of the axle shaft. Use a punch or drift and hammer, if needed.
5. Install the fasteners and tighten to correct torque value. See the
Workshop Manual.
