AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
•Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should
always shift the transmission into PARK, remove
the key fob from the ignition, and apply the
parking brake. Once the key fob is removed from
the ignition, the shift lever is locked in the PARK
position, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.(Continued)

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
Column Shifter
There is an override for the BTSI that allows you to move
the shift lever out of the PARK position if an electrical
system malfunction occurs (i.e., dead battery).
1. Turn the ignition switch to the ACC or ON position
without starting the engine.
2. Tilt the steering wheel to the full up position
3. Firmly set the parking brake.
4. Press and maintain firm pressure on the brake pedal.

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL position into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position. On four-wheel drive ve-
hicles be sure that the transfer case is in a drive position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.(Continued)
WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever back and forth without first
pulling it toward you after you have set it in
PARK. Make sure it is in PARK before leaving the
vehicle.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your foot is firmly on the brake pedal.
REVERSE
This range should be used only after the vehicle has come
to a complete stop.
64 STARTING AND OPERATING
Page 66 of 170

NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range provides underdrive first, second and third
gears, direct fourth gear and overdrive fifth and sixth
gears. The shift into overdrive fifth and sixth gear occurs
only after the transmission has completed the shift into
fourth gear. No other movement of the shift mechanism
is required to complete the 4–5 or 5–6 gear shifts.
Upshifts into both overdrive gears, fifth and sixth, will be
delayed when the transmission fluid temperature is
below 40°F (4.5°C) or above 240°F (115.5°C).NOTE:
Use caution when operating a heavily loaded
vehicle in second or first gear in high ambient tempera-
tures as torque converter slip can impose significant
additional heat load on the cooling system.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fifth and sixth (Overdrive). The
transmission will automatically shift from DRIVE to
Overdrive if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the “TOW/HAUL” switch has not been activated;

REVERSE
This range should be used only after the vehicle has come
to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range provides all forward gears, including fourth
gear direct, fifth and sixth. Use this range for most city
and highway driving. Upshifts into both overdrive gears,
fifth and sixth, will be delayed when the transmission
fluid temperature is between -4°F (-20°C) and 41°F (5°C).
During very cold conditions when the transmission fluid
is below -4°F (-20°C), the transmission will be limited to
third gear. Normal operation will return after the trans-
mission fluid warms up.NOTE:
Use caution when operating a heavily loaded
vehicle in second or first gear selections in high ambients
as torque converter slip can impose significant additional
heat load on the cooling system.
Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fifth and sixth gear. The transmis-
sion will automatically shift from DRIVE to fifth or sixth
gear if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 38 mph
(61 km/h) for fifth gear and 50 mph (80 km/h) for
sixth gear;
•the “TOW/HAUL” switch has not been activated
(sixth gear is inhibited in “TOW/HAUL” mode);

NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
normal. Pressing the “TOW/HAUL” switch when the
transmission is sufficiently warm will demonstrate
that the transmission is able to shift into and out of
Overdrive.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds of shifting from
PARK into any other gear position.
MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
CAUTION!
Never drive with your foot resting on the clutch
pedal, or attempt to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch.
NOTE: During cold weather, you may experience in-
creased effort in shifting until the transmission fluid
warms up. This is normal.

POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with either the AS68RC
automatic six-speed or G-56 manual six-speed transmis-
sions, will allow for an aftermarket upfit with a transmis-
sion driven PTO (power take off). The customer will have
the ability to operate the PTO in either a “stationary” or
“mobile” mode. The vehicles will be factory set to the
“stationary” mode. In order to select the “mobile” mode
an authorized dealership is required to modify the vehi-
cle’s settings using their proprietary authorized dealer
service tool.
AS68RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS68RC) operates at
torque converter turbine speed. The turbine speed will be
less than engine speed when the torque converter clutch
is not engaged and will be same as engine speed when
the torque converter clutch is engaged.
Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Be in PARK position (vehicles equipped with auto-
matic transmission)
•Upfitter provider (on/off) switch has been activated
•Parking brake applied (vehicles equipped with
manual transmission)
•Brake pedal must not be applied
•Vehicle engine must be running
•No vehicle, brake or clutch switch faults present
•PTO must be correctly installed using the vehicle
provided circuits
