Using this Manual

Please take the time to get acquainted with

your vehicle by reading this Operator’s

Manual. We recommend that you read and

understand this manual from beginning to

end before you operate this equipment.

This manual contains useful information for

the safe and efficient operation of this

equipment. It also provides service

information, with an outline for performing

safety checks and basic preventive

maintenance inspections. We have tried to

present the information you’ll need to learn

about functions, controls, and operation—

and to present it as clearly as possible. We

hope you’ll find this manual easy to use.

There will be times when you need to take

this manual out of the glovebox. When you

do, please be sure to return it when you

are finished using it. That way it will be

there when you need it the next time or

when you pass the vehicle on to the next

user.

NOTE

After you’ve read this manual, it should

stored in the cab for convenient ref-

erence and remain with this truck

when sold.

to the instructions that pertain to just your

vehicle. In addition, if your vehicle is

equipped with special equipment or options

not discussed in this manual, consult your

dealer or the manufacturer of the

equipment.

There are several tools built into this

manual to help you find what you need

quickly and easily

. First is the Quick Table

of Contents. Located at the front of the

manual, this lists the main subjects

covered and gives section numbers where

you can find these subjects. Use the Quick

Table of Contents to find information on a

large subject like “Maintenance.” Cross-

referenced citations also help you get the

information you need. If some other part of

the manual contains further information on

the subject you are reading about, we’ll

indicate that in a cross-reference like this:

General Safety

Instructions

Important safety notices about operating

and servicing your engine.

WARNING

Improper practices, carelessness, or

ignoring

any warnings may cause

death, personal injury, equipment or

property damage.

Before performing any repair, read and

understand all of the safety precautions

and warnings. The following is a list of

general safety precautions that must be

followed to provide personal safety

. Failure

to follow these instructions may cause

death or injury. Special safety precautions

are included in the procedures when they

apply.

Keep in mind that even a well maintained

vehicle must be operated within the range

of its mechanical capabilities and the limits

of its load ratings. See the Weight Ratings

label on the driver's door edge.

Every new vehicle is designed to conform

to all Federal Motor Vehicle Safety

Standards applicable at the time of

manufacture. Even with these safety

features, continued safe and reliable

operation depends greatly upon regular

vehicle maintenance. Follow the

maintenance recommendations found in

Preventive Maintenance section. This will

help preserve your investment.

Make sure your vehicle is in top working

condition before heading out on the road, it

is the responsible driver's duty to do so.

Inspect the vehicle according to the

Driver's Check List.

•

Use the proper tool for manually

rotating the engine. DO NOT

attempt to rotate the crankshaft by

pulling or prying on the fan. This

practice can cause death, personal

injury, equipment damage, or

damage to the fan blades, causing

premature fan failure.

• Work areas should be dry, well lit,

well ventilated, free from clutter,

loose tools, parts, ignition sources

and hazardous substances.

• Wear protective glasses and

protective shoes when working.

• DO NOT wear loose-fitting or torn

clothing. Tie back and/or tuck in

long hair. Remove all jewelry when

working.

• Before beginning any repair,

disconnect the battery (negative [-]

cable) and discharge any

capacitors.

• Put a “DO NOT OPERATE” tag in

the operator's compartment or on

the controls.

• Allow the engine to cool before

slowly loosening the coolant filler

cap to relieve the pressure from the

cooling system.

WARNING

Removing the fill cap on a hot engine

can

cause scalding coolant to spray

out and burn you badly. If the engine

has been in operation within the previ-

ous 30 minutes, be very careful in re-

moving the fill cap. Protect face,

hands, and arms against escaping flu-

id and steam by covering the cap with

a large, thick rag. DO NOT try to re-

move it until the surge tank cools down

or if you see any steam or coolant es-

caping. In any situation, remove the

cap very slowly and carefully. Be ready

to back off if any steam or coolant be-

gins to escape.

burns.

• Always use tools that are in good

condition. Make sure you have the

proper understanding of how to use

the tools before performing any

service work. Use only genuine

replacement parts from PACCAR.

• Always use the same fastener part

number (or equivalent) when

replacing items. DO NOT use a

fastener of lesser quality if

replacements are necessary. (e.g.,

Do not replace a 10.9 grade with

8.8 grade fastener.)

• Always torque fasteners and fuel

connections to the required

specifications. Overtightening or

under-tightening can allow leakage.

• Close the manual fuel valves prior

to performing maintenance and

repairs, and when storing the

vehicle inside.

Clutch Abuse Protection

CAUTION

The PACCAR Automated Transmis-

sion

clutch can overheat and slip with

improper use.

• DO select the lowest possible start

gear for the application. If moving

slowly is required, select 1st or R1.

•

DO use the Service Brakes and let

Hill Start Aid assist you when

launching on an incline.

• Do NOT use the accelerator pedal

to hold the vehicle on an incline.

(Use Service Brakes).

• Do NOT use the accelerator pedal

to stop roll back on an incline after

Hill Start Aid disengages. (Use

Service Brakes and then relaunch).

•

If the PACCAR Automated

Transmission clutch does start to

overheat, the display will show

“CA” along with a warning tone. If

“CA” is active in the gear display,

immediately discontinue the

operation that is being performed

which is causing the clutch to

overheat.

• If the driver continues abusive

operation, the system will either

open the clutch if the

accelerator pedal is not applied

or close the clutch if the

accelerator pedal is applied.

• If the abuse continues, the

system will open the clutch and

take away accelerator pedal

control for a short period of time

to allow the clutch to cool down.

Urge to Move may be

inoperable when the clutch is

overheated.

Engine Overspeed Protection

• The transmission system will

upshift if necessary to prevent

DRIVING - Features

22 Y53-1272-1B1 (08/17)

engine overspeed in Drive,

MANUAL and LOW modes.

Shuttle Shifting

•

Shuttle shifting from Reverse to

any forward mode is only allowed if

the vehicle speed is approximately

zero.

Intelligent Start Gear Selection

• Intelligent Start Gear Selection will

automatically select the start gear

depending on inputs such as load,

grade and axle/transmission ratio.

• The start gear selection can be

changed using the up/downshift

request, however, if the selection

requested could cause damage or

engine lugging the request will be

denied and an audible tone will

sound.

Skip Shifting

• The Automated Transmission will

shift multiple gears at one time

(skip shift) with moderate to high

accelerator pedal input while in

Drive mode, up to 8th gear.

Auto Neutral

•

The transmission system will

automatically shift to neutral if the

vehicle is left in Drive and the

parking brakes are set.

• “AN” will appear in the gear display.

The driver must then select the

desired forward or reverse mode

with the service brake applied.

Load Based Shifting

• The transmission system will adapt

to the conditions of the vehicle to

change the shift points based on

the followings inputs:

• Vehicle grade

• Engine RPM

• Accelerator pedal position

• Vehicle load

• After changing loads or powering

up the transmission system needs

to relearn these inputs for the first

few shifts to make the proper

adjustments.

Coast Mode

• When coasting to a stop, in Drive

mode, on level terrain the

transmission system may not

downshift into lower gears. This

allows the transmission to coast to

a stop.

Cruise Control

•

This transmission system is

compatible with cruise control.

Neutral Coast Mode

Neutral Coast Mode allows the

transmission to disengage the driveline by

pulling out of gear on slight downhill

grades, where little to no engine power is

required, when the vehicle is in cruise

control and the transmission is in Drive

mode.

• When Neutral Coast Mode is

active, the engine will drop to idle

speed and the transmission will

disengage.

• The gear display may flash a gear

number or indicate Neutral when

Neutral Coast Mode is active,

depending upon specific OEM

implementation.

• If a flashing number is indicated in

the gear display, this represents the

gear that the transmission will

select when it is necessary to

engage a gear

• The transmission will exit Neutral

Coast Mode and reengage an

appropriate gear under any of the

following conditions:

• Vehicle brakes are applied

• Driver depresses accelerator

pedal

• Cruise control is canceled

• A mode other than Drive is

selected

• Driver performs up/downshift

requests

• Cruise high or low set speeds

are exceeded

• Maximum vehicle grade is

exceeded

• Request by an adaptive cruise

system

• Various brand names may be used

for Neutral Coast systems.

Urge to Move

Urge to Move allows the vehicle to

automatically start moving when the

transmission is in gear and the driver

releases the service brake. After the

vehicle has launched the vehicle will creep

at a constant speed at engine idle without

the need to apply the accelerator pedal.

The configuration is useful for stop and go

applications allowing the vehicle to launch

and creep without applying the accelerator.

Creep Mode

Creep allows the vehicle to be driven at a

constant speed at engine idle without the

need to apply the accelerator pedal. The

configuration is useful for slow speed

applications where steady vehicle speed is

required. Upshifts and downshifts can be

requested to increase or decrease vehicle

speed.

What is a Maintenance

Program?

Preventive maintenance program begins

with the daily checks. Routine vehicle

checks can help avoid many large,

expensive, and time consuming repairs.

The vehicle will operate better, be safer,

and last longer. Neglect of recommended

maintenance can void your vehicle’s

warranty. Some maintenance operations

demand skills and equipment you may not

have. For such situations, please take your

vehicle to an authorized Service Center.

WARNING

Always support the vehicle with appro-

priate safety stands if it is necessary to

work underneath the vehicle. A jack is

not adequate for this purpose. Failure

to comply may result in death, person-

al injury, equipment or property dam-

age.

WARNING

When working underneath the vehicle

without

appropriate safety stands but

with the wheels on the ground (not

supported), make sure that (1) the ve-

hicle is on hard level ground, (2) the

parking brake is applied, (3) all wheels

are blocked (front and rear) and (4) re-

move the ignition key so that the en-

gine cannot be started. Failure to com-

ply may result in death, personal in-

jury, equipment or property damage.

The following pages contain a table of

maintenance tasks with the related

intervals for each task on the right side of

the table. The top of the table displays a

guide to a maintenance interval and its

schedule. Some tasks are dependent on

the vehicle application. These tasks will be

shown as separate tasks and will have the

words “ON HIGHWAY”, “CITY DELIVERY”

or “OFF-HIGHW

AY” after the description.

These tasks are differentiated because

they are dependent on the vehicle’s

operating environment. On highway is

defined for applications where the vehicle

is NOT used off of a paved road during

normal operation. City Delivery is defined

for applications where frequent start and

stopping is required during normal

operation and the highway is used

infrequently and for short periods of time.

Off highway is defined for applications

where the vehicle may be driven off the

pavement on a regular basis, even if it is

an infrequent basis and/or for a brief time

period. Please contact an authorized

service dealership if there are questions

regarding which interval to follow. Consult

the supplier for specific recommendations

where discrepancies develop between

these recommendations in this table and

component supplier recommendations.

What is the Air System?

Important safety information about your

vehicle's air system.

The operation of the vehicle’s braking

system and many vehicle accessories

depends upon the storage and application

of a high-pressure air supply

MAINTENANCE - What is the Air System?

Y53-1272-1B1 (08/17) 29

WARNING

Do not attempt to modify, alter, repair

or disconnect any component of the air

system. Repairs or modifications to the

air

system, other than what is descri-

bed in this section, should only be per-

formed by an authorized dealer. Fail-

ure to comply may result in death or

personal injury.

WARNING

Prior to the removal of any air system

component,

always block and hold the

vehicle by a secure means other than

the vehicle's own brakes. Depleting air

system pressure may cause the vehi-

cle to roll unexpectedly resulting in an

accident causing death or personal in-

juries. Keep hands away from cham-

ber push rods and slack adjusters,

they may apply as system pressure

drops.

WARNING

After completing any repairs to the air

system,

always test for air leaks, and

check the brakes for safe operation

before putting the vehicle in service.

Failure to comply may result in death,

personal injury, equipment or property

damage.

WARNING

Never connect or disconnect a hose or

line

containing air pressure. It may

whip as air escapes. Never remove a

component or pipe plug unless you are

certain all system pressure has been

depleted. Failure to comply may result

in death, personal injury, equipment or

property damage.

WARNING

Never exceed recommended air pres-

sure

and always wear safety glasses

when working with air pressure. Never

look into air jets or direct them at any-

one. Failure to comply may result in

death,

personal injury, equipment or

property damage.

WARNING

Never attempt to disassemble a com-

ponent

until you have read and under-

stood recommended procedures.

Some components contain powerful

springs and injury can result if not

properly disassembled. Use only prop-

er tools and observe all precautions

pertaining to use of those tools. Failure

to comply may result in death, person-

al injury, equipment or property dam-

age.

MAINTENANCE - What is the Air System?

30 Y53-1272-1B1 (08/17)

WARNING

Completely bypassing a Bendix®

ADIS

air dryer will bypass the system’s

pressure protection valves. This could

lead to loss of air pressure or damage

to the vehicle’s air system, which could

cause an accident involving death or

personal injury. Always adhere to the

manufacturer’s procedure if it is nec-

essary in an emergency to temporarily

bypass an ADIS series air dryer. Fail-

ure to comply may result in death, per-

sonal injury, equipment or property

damage.

WARNING

If a different air dryer brand or model is

installed

on the vehicle other than

what was originally installed, it could

cause the air system to not perform

correctly unless the full air system de-

sign is reviewed and modifications

made to comply with Federal Motor

Vehicle Safety Standards (FMVSS)

121 AirBrake Systems. Failure to

abide by this warning and maintain

compliance to FMVSS 121 could

cause

loss of vehicle control and may

lead to death or serious personal in-

jury.

WARNING

If the supply and service air tanks are

not

drained at the recommended fre-

quency, water could enter the air lines

and valves. This could cause corrosion

or blockage, which could compromise

the brake system safety and potential-

ly cause an accident. Failure to comply

may result in death, personal injury,

equipment or property damage.

Your vehicle’s compressor takes outside air

and compresses it, usually to 100-120 psi

(689-827 kPa). The compressed air then

goes to the reservoirs to be stored until

needed. When you operate your air

brakes, the stored compressed air flows

into the chambers where it is used to apply

your truck and trailer brakes. That is why

when you push down on your brake pedal,

you don’t feel the same amount of

pressure on the pedal that you do when

you apply the brakes on your car. All you

are doing on your truck is opening an air

valve to allow air to flow into the brake

chambers. Contamination of the air supply

system is the major cause of problems in

air-operated components such as brake

valves, and suspension height control

valves. T

o keep contaminants to the lowest

possible level, follow these maintenance

procedures.

Daily Checks

• Drain moisture from the supply and

service air tanks.

• Operate air devices to circulate

lubricants within the unit.

Periodically

• Clean filter screens ahead of the

valves by removing the screens

and soaking them in solvent. Blow

them dry with pressurized air

before reinstalling them.

Twice a Year

• Maintain the air compressor to

prevent excessive oil by-pass. See

your maintenance manual for

details.

• Replace worn seals in valves and

air motors as they are needed.

MAINTENANCE - What is the Air System?

Y53-1272-1B1 (08/17) 31

Air Dryer Maintenance

Vehicles equiped with a PACCAR

Transmission will have an air dryer fitted

with an oil-coalescing desiccant cartride.

This air dryer cartridge must be replaced

every 1 year regardless of mileage.

CAUTION

Replace oil-coalescing desiccant air

dryer

cartridge every 1 year regardless

of mileage. Only use oil-coalescing

desiccant replacement cartridge when

replacing. Failure to perform this main-

tenance task will void the PACCAR

Transmission warranty and may result

in expensive transmission damage.

Proper Transmission

Lubrication

Proper lubrication procedures are key to a

good all-around maintenance program. If

the lubricant is not doing its job or if the

lubricant level is ignored, all other

maintenance procedures are not going to

keep the transmission running or assure

long transmission life.

ransmission internal parts are amply

lubricated if these procedures are closely

followed:

1. Maintain lubricant level and inspect

regularly.

2. Follow maintenance intervals, see

Transmission Lubrication Change

Intervals on page 33.

3. Use the correct grade and type of

lubricant, see PACCAR

Transmission Lube Specification on

page 37.

4. Buy lubricant from an approved

dealer.

Mixing of Oil Types

CAUTION

Do not mix engine and gear oil in the

same transmission. Mixing engine and

gear oils could cause damage to the

transmission.

Engine oils and gear oils may not be

compatible; mixing can cause breakdown

of the lubricant and affect component

performance. When switching between

types of lubricants, all areas of each

fected component must be thoroughly

flushed.

NOTE

For a list of Approved Synthetic Lubri-

cants, see vehicle operator manual.

NOTE

Additives and friction modifiers must not

be introduced.

Proper Transmission Lubrication

Level

Make sure the transmission lubricant is

level with the bottom of the fill opening.

Being able to reach the lubricant with your

finger does not mean the lubricant is at the

proper level.

MAINTENANCE - Air Dryer Maintenance

32 Y53-1272-1B1 (08/17)

NOTE

Before checking the oil level, the en-

gine

must be idling and the transmis-

sion in neutral for at least 2 minutes.

Lubricant temperature must be be-

tween 60 °F and 120 °F (15.5 °C and

48.8 °C).

If the transmission operating angle is more

than 12° (or roughly a 21% grade),

improper lubrication will occur

. The

operating angle is the transmission

mounting angle in the chassis plus the

percent of upgrade (expressed in degrees).

ransmission Lubrication Change

Intervals

Lubricant changes should be based on a

combination of the intervals shown in

vehicle operator manual Lubrication

Specification Manual, and user judgment

based on the application and operating

environment. Extending drain intervals

beyond those shown in the tables is not

recommended and will put warranties at

risk.

Inspect the transmission exterior for leaks.

Look around the oil filter and exterior seals

for damage and replace as necessary.

On-Highway

Check fluid levels and inspect for leaks at

regular PM maintenance intervals, not to

exceed 12,000miles. Drain and replace

lubricant every 500,000 miles / 800,000

km.

Off-Highway

Check fluid levels and inspect for leaks

every week. Drain and replace lubricant

interval should not exceed 60,000 mi /

96,000 km / 6 Months.

Vehicle Towing

When towing the vehicle, the output shaft

of the transmission must not be allowed to

spin or turn. If the vehicle is towed with the

drive wheels still in contact with the road

surface, the vehicle axle shafts or driveline

must be removed or disconnected.

CAUTION

Always follow proper manufacturer

towing procedures. Failure to follow

proper towing procedures could result

in damage to the transmission.

How to Drain Fluid

Use a drain pan under the

transmission drain plug to collect

oil from the bottom of the

transmission.

MAINTENANCE - Vehicle Towing

Y53-1272-1B1 (08/17) 33

2. Make sure the oil temperature is

cool.

Clean around drain plug and

remove plug.

4. Allow transmission oil to drain out.

5. Clean drain plug and torque as

required.

How to Fill Fluid

1. Remove transmission oil fill plug.

2. Make sure drain plug is properly

installed.

3. Fill with approved oil until the oil

starts flowing out the fill hole.

4. Clean, install, and properly and

torque fill plug.

Troubleshooting

Diagnostics

In the event there is a problem with an

Automated Transmission, there are three

primary tasks the driver should perform:

1. Note the driving condition under

which the problem occurred.

2. Note the condition of the

transmission under which the

problem occurred (i.e. operation

mode (Drive, MANUAL, LOW),

current gear, engine speed, etc.).

3. Reset system.

Transmission Reset Procedure

In some cases, proper transmission

operation can be restored by “resetting” the

Transmission Control Module (TCM). Use

the following procedure to reset the TCM.

1. Continue to drive the vehicle to a

safe location before selecting “N”

NEUTRAL.

NOTE

Once “N” NEUTRAL is selected, a gear

engagement may not be allowed de-

pending on the nature of the problem.

2. Place the Transmission Driver

Interface Device in Neutral “N”.

Set the vehicle parking brake.

WARNING

Apply parking brake and follow vehicle

manufacturer parking instructions. Fail-

ure to follow these instructions could

cause unintended vehicle movement re-

sulting in death, serious injury or dam-

age to property

4. Turn the vehicle ignition to the “off”

position.

Wait at least 2 minutes.

6. Restart the engine.

7. If the problem continues, contact a

service facility to have the vehicle

and transmission system

evaluated.

Transmission Air Supply

For optimal performance, the PACCAR

Automated Transmission requires a

nominal air supply operating range

between 90 psi (5.9 bar) and 130 psi (9.0

bar).

MAINTENANCE - How to Fill Fluid

34 Y53-1272-1B1 (08/17)
