2008 CHEVROLET KODIAK transmission

Eaton®Fuller®Nine and Ten-Speed
Non-Synchronized Manual
Transmissions
If your vehicle has one of these transmissions the
engine rpm and road speed must match when upshifting
and downshifting. The label above the windshield will
tell you the operating basics you need to know.
The following are driving tips.
•Always choose an initial starting gear suitable for
the load and terrain.
•Always use double-clutching procedures when
shifting.
•Never move the range shift lever to the LO speed
gear position after HI range preselection, or
anytime the transmission is in the HI range.
•Never move the range knob or lever with the shift
lever in NEUTRAL while the vehicle is moving.
•Never make a range shift while moving in
REVERSE (R).
Clutch Brake (Vehicles with
Non-Synchronized Transmission)
A clutch brake is used to stop transmission input shaft
rotation so that FIRST (1) or REVERSE (R) gear
selection can be initiated when the vehicle is at a
standstill and the engine is idling.
Press the clutch pedal all the way down to the floorboard
to apply the clutch brake.
When using the clutch brake, disengage the clutch
pedal and shift the transmission into either the initial
starting gear or REVERSE (R). If the tooth-butting
occurs between the clutching teeth, re-engage the clutch
while applying light pressure to the shift lever. This
will provide for a smooth shift into either FIRST (1) or
REVERSE (R) gear.
Notice:Using the clutch brake for shifting into any
gear other than FIRST (1) or REVERSE (R) may
cause premature wear of the clutch brake and make
gear shift effort more difficult. Do not use the
clutch brake for shifting after engaging FIRST (1) or
REVERSE (R).

Power Take-Off (PTO)
Your vehicle may have
power take-off (PTO). The
PTO switch is located
on the instrument panel.
An indicator in the switch comes on to show PTO is
active. SeeHigh Idle System on page 2-20for
more information.
A PTO is a gearbox or mechanical device used to
transmit mechanical power from the powertrain, through
gears or a transmission, to another mechanical or
hydraulic device. Before using a PTO, refer to the
manufacturer’s or installer’s instructions.
Four-Wheel Drive
If your vehicle has four-wheel drive, you can send the
engine’s driving power to all four wheels for extra
traction. To get the most satisfaction out of four-wheel
drive, you must be familiar with its operation. Read
the part that follows before using four-wheel drive. You
should use two-wheel drive high for most normal
driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time can
cause premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in Four-Wheel
Drive for extended periods of time.

m(Two-Wheel High):This setting is for driving in
most street and highway situations. The transfer
case does not drive the front axle in two-wheel drive.
The front-axle spins if the front wheel hubs are locked.
Be sure to unlock the hubs to achieve the best fuel
economy.4
m(Four-Wheel High):Use Four-Wheel High when
you need extra traction, such as on snowy or icy
roads or in most off-road situations. Be sure the front
wheel hubs are locked when you want to drive in
Four-Wheel High.
4
n(Four-Wheel Low):This setting sends maximum
power to all four wheels. You might choose Four-Wheel
Low if you are driving off-road in deep sand, deep
mud, and climbing or descending steep hills. Be sure
the front wheel hubs are locked when you want to drive
in Four-Wheel Low.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be injured. If you are going to leave
your vehicle, set the parking brake and shift
the transmission to PARK (P) and make sure
the transfer case is in a drive gear.
2-34

Notice:If your vehicle has an Allison®transmission
and you try to put the transmission in PARK (P)
while the transfer case is in Four-Wheel Low,
the transmission might not go into PARK (P) and
could damage your vehicle. When parking your
vehicle, make sure the transfer case is in Two-Wheel
High or Four-Wheel High.
NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.
Shifting Into Four-Wheel High
Turn the knob to four-wheel high. This can be done at
3 mph or less, while you are shifting out of Four-Wheel
Low. The indicator light flashes while shifting. It
remains on after the shift is complete. Be sure to lock
your front hubs.
Shifting Into Two-Wheel High
Turn the knob to Two-Wheel High. This can be done
at 3 mph or less, while you are shifting out of
Four-Wheel Low.
Shifting Into Four-Wheel Low
To shift to Four-Wheel Low, the vehicle’s engine must
be running and the vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission
in NEUTRAL (N). The preferred method for shifting
into Four-Wheel Low is to have your vehicle moving
1 or 2 mph (1.6 to 3.2 km/h). Turn the knob to
Four-Wheel Low. You must wait for the Four-Wheel Low
indicator light to stop flashing and remain on before
shifting the transmission into gear. Be sure to lock the
front hubs.
Notice:Shifting the transmission into gear before
the Four-Wheel Drive Low indicator light has stopped
ashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for the
Four-Wheel Drive Low indicator light to stop ashing
before shifting the transmission into gear.
If you turn the knob to Four-Wheel Low while your
vehicle is in gear and/or moving, the Four-Wheel Low
indicator light flashes for 30 seconds and does not
complete the shift unless your vehicle is moving less
than 3 mph (4.8 km/h) and the transmission is in
NEUTRAL (N). After 30 seconds, the transfer case
returns to the setting last chosen. If your vehicle is in
gear and moving less than 3 mph (4.8 km/h), the
transfer case shifts to Four-Wheel High.
2-35

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, your vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N) and the engine running. The preferred
method for shifting out of Four-Wheel Low is to have your
vehicle moving 1 or 2 mph (1.6 to 3.2 km/h). Turn the
knob to Four-Wheel High or Two-Wheel High. You must
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop flashing and remain on before
shifting the transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel High or Two-Wheel High indicator
light has stopped ashing could damage the transfer
case. To help avoid damaging your vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop ashing before shifting
the transmission into gear.
If the knob is turned to Four-Wheel High or Two-Wheel
High while your vehicle is in gear and/or moving, the
Four-Wheel High or Two-Wheel high indicator light
flashes for 30 seconds. It will not complete the shift
unless your vehicle is moving less than 3 mph (5 km/h)
with the transmission in NEUTRAL (N).
Shifting Into NEUTRAL
Before shifting the transfer case to NEUTRAL, first
make sure the vehicle is parked so that it will not roll.

Shifting Out of NEUTRAL
To shift the transfer case out of NEUTRAL, do the
following:
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Apply the regular brake pedal.
3. Turn the ignition to ON/RUN with the engine off.
4. Put the transmission in NEUTRAL (N).
5. Turn the transfer case knob to the desired shift
position (Two-Wheel High, Four-Wheel High,
Four-Wheel Low).
6. After the transfer case has shifted out of NEUTRAL,
the indicator light goes out.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.7. Release the parking brake.
8. Start the engine and shift the transmission lever to
the desired position.
Excessively shifting the transfer case into or out of the
different modes can cause the transfer case to enter the
shift protection mode. This protects the transfer case from
possible damage and only allows the transfer case to
respond to one shift per 10 seconds. The transfer case
can stay in this mode for up to three minutes.
Parking
{CAUTION:
If you do not park your vehicle properly, it can
roll. If you have left the engine running, it can
move very quickly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on level ground, follow the
steps below.
2-37

Parking a Vehicle With the Two-Speed
Rear Axle
1. With the engine running, shift the two-speed
rear axle into low. To be sure it is in low,
you will need to move the vehicle in gear just
a little.
2. Hold the regular brake pedal down with your
right foot.
3. Apply the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking

{CAUTION:
If you apply any one of the air brake parking
controls while the vehicle is moving, your rig
will stop suddenly. If you are not ready for
this, you or others could be injured. Do not
apply any one of these controls while you are
driving, unless you have to make an
emergency stop.
If the air pressure drops below 60 to 70 psi
(413 to 482 kPa), the primary brake light and warning
buzzer will come on. If the air pressure drops to
35 to 45 psi (241 to 310 kPa), the red trailer air supply
knob will automatically pop out and apply the spring
brakes on the trailer.
If the air pressure drops to 35 to 45 psi (241 to 310 kPa),
the yellow park brake knob will automatically pop out
and apply the spring brakes on the truck or tractor.
If you ever have a complete loss of air so that your air
brakes automatically apply, there is a way that the
tow operator can release the parking brakes to tow the
vehicle. SeeTowing Your Vehicle on page 4-24.
Parking Brake Burnish Procedure
All vehicles which have hydraulic brakes have a parking
brake. It is recommended that the parking brake be
burnished as part of the new vehicle break-in. The
parking brake will work best after it has been burnished
following these instructions:
1. Make sure that there is no other traffic around,
bring the vehicle speed up to 20 mph (32 km/h)
and apply the parking brake. Let the vehicle come
to a complete stop. Apply the base brakes and
disengage the parking brake.
2. Repeat the burnishing procedure in Step 1 a total
of 10 times
3. Between stops, drive the vehicle about
2.5 miles (4 km)
Notice:Driving with the parking brake on can
damage the transmission and brake system parts.
Verify that the parking brake is fully released and the
brake warning light is off before driving.
