automatic transmission CHEVROLET KODIAK 2009 User Guide

Eaton®Fuller®Five and Six-Speed
Transmissions and TTC Spicer
Seven-Speed Transmissions
These transmissions have gears that automatically
synchronize when you shift up or down (except 1 (First)
gear on the five-speed and seven-speed transmission
which is unsynchronized). Choose the gear that will
maintain the road speed you want while keeping
the engine above two-thirds of the governed speed.
When the engine speed drops below two-thirds of the
governed speed, shift into the next lower gear before
your engine begins to lug. When you shift down, be sure
to double-clutch if required.
Eaton®Fuller®Nine and Ten-Speed
Non-Synchronized Manual
Transmissions
If the 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 N (Neutral) while the vehicle is moving.
•Never make a range shift while moving in
R (Reverse).
Clutch Brake (Vehicles with
Non-Synchronized Transmission)
A clutch brake is used to stop transmission input shaft
rotation so that 1 (First) or R (Reverse) 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 R (Reverse). 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 1 (First) or R (Reverse) gear.
Notice:Using the clutch brake for shifting into any
gear other than 1 (First) or R (Reverse) 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 1 (First) or R (Reverse).

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 brake pedal down.
3. Apply the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
4. Shift the transmission to N (Neutral) for manual
transmission or P (Park) for automatic transmission.
Two-Speed Rear Axle
The Two-Speed rear axle lets the driver select Low
Range and High Range. Low Range provides good
starting torque and pulling power. When selecting High
Range the axle allows for higher road speed and
fuel economy.For better performance during off-road or under a heavy
load, shift the axle into Low Range and then operate
the transmission normally.
For better performance on the highway, shift the axle to
High Range and operate the transmission normally.
High or Low Range can be used when additional shifts
between transmission gears is needed while driving
on grades and for better fuel economy.
Notice:Driving in Low Range above 50 mph
(80.5 kph) will damage driveline components. Drive
below 50 mph (80.5 kph) in Low Range.
If the vehicle has this feature, there is a label on the
headliner above the windshield or in another place near
the driver that shows how to use it. Be sure to follow
the directions carefully.

Two-Speed Rear Axle Shift Control
Operation
The rear axle shift control
switch for automatic and
manual transmissions
is located in the instrument
panel switchbank.
Press the bottom of the switch for High Range and the
top of the switch for Low Range. The switch indicator
light comes on when the High Range is selected.
Always start the vehicle in motion with the two-speed
axle in low range.
Shifting on a Downgrade
Do not shift the two-speed axle when driving on a
downgrade. The speed of the vehicle moving downhill
may make it hard to shift the axle into either Low or High
Range.
Shifting
Upshifting the Axle
To shift from Low to High Range:
1. Press the bottom of the switch to shift the axle
control from Low to High.
2. Release the accelerator pedal until the shift applies.
3. Then push the accelerator pedal.
Axle upshift can be abrupt, causing the vehicle to jerk.
Release the accelerator slowly for a smooth shift.
For manual transmissions, use the clutch while pressing
the accelerator for a smooth shift.
Downshifting the Axle
To shift from High to Low Range:
1. Press the top of the switch to shift from High to Low
Range.
2. Release the accelerator pedal.
3. Then push the accelerator pedal slowly until the
axle shifts.

{CAUTION:
If you apply any one of the air brake parking
controls while the vehicle is moving, the 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 warning light and
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 the 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 4-23.
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.
2-43

4. Fully set the parking brake.
5. Shift the transmission to P (Park) or N (Neutral).
6. Idle the engine. If you used the idling control knob to
increase the engine speed, restore it all the way to
the left to reduce the engine speed.
7. If the vehicle has a Power Take Off (PTO), turn the
PTO off. SeePower Take-Off (PTO) on page 2-30.
8. Press the DPF switch in the instrument panel
switchbank. SeeInstrument Panel Switchbank
on page 3-18. The green DPF indicator light comes
on, the exhaust gas control valve operates,
engine idle speed automatically increases, and DPF
cleaning begins. Do not leave the vehicle
unattended during manual cleaning.9. When both the green and the yellow or red DPF
indicator lights go off, cleaning is completed.
Manual cleaning is normally completed in about
30 minutes.
Under certain operating conditions, manual cleaning
might not be able to be performed, even if the soot level
in the DPF requires cleaning. This can occur because of
low coolant temperature, low battery voltage, high
exhaust temperature or immediately after starting the
vehicle. When manual cleaning is requested and coolant
temperature is low, an engine warm-up cycle is started.
The green indicator light will come on, the exhaust gas
control valve operates, and engine rpm increases to help
raise engine coolant temperature. When operating
conditions allow, cleaning will begin.

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-45.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when it is on
fairly level ground, always set the parking brake
and move the automatic transmission shift lever to
P (Park), or the manual transmission shift lever to
Neutral.
Follow the proper steps to be sure the vehicle will
not move.

Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicles speed, load and the steepness of the hills.
When going up steep hills, you may want to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear to
keep your speed down. When the brake or clutch is
applied the cruise control will shut off.
For vehicles with the exhaust brake option and the
exhaust brake is turned on, the exhaust brake may come
on and try to slow down the vehicle to the set cruise
control speed if the vehicle has accelerated past the set
cruise control speed while going downhill.
Ending Cruise Control
There are four different ways to turn off the cruise
control:
•Step lightly on the brake pedal (manual and
automatic transmissions).
•Press the clutch pedal to the floor (manual
transmissions).
•Move the cruise switch to9.
•Shift the transmission to N (Neutral).
Erasing Speed Memory
The cruise control set speed memory is erased when
the ignition is turned off.
