transmission fluid JEEP LIBERTY 2004 KJ / 1.G Owners Manual

14. Cruise Indicator Light
This indicator lights when the speed control
system is turned ON.
15. Oil Pressure Warning Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on, have the system checked by your autho-
rized dealer.
If the warning light comes on and remains on while
driving, stop the vehicle and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED. Also, a single chime will sound.
16. Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur with
severe usage such as trailer towing or snow plowing. Ifthis light comes on, stop the vehicle and run the engine at
idle or faster, with the transmission in N (Neutral) until
the light goes off.
17. Part Time Indicator Light Ð If Equipped
This light alerts the driver that the vehicle is in
the PART TIME four±wheel drive high range
mode, and the front and rear driveshafts are
mechanically locked together forcing the front and rear
wheels to rotate at the same speed.
18. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the light comes on, it may indi-
cate that the parking brake is applied, or there
is a low brake fluid level. On vehicles equipped with
Anti-Lock brakes (ABS), it may also indicate an ABS
malfunction that could lead to reduced braking perfor-
mance.

CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
²Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
²Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
²Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
²Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
²When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
²Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
²During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
²Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
²When ªrockingº a stuck vehicle by shifting between a
forward gear and reverse, do not spin wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
214 STARTING AND OPERATING

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.NOTE:
²The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1±3 miles (1.6±4.8 km) of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into ªOverdriveº when cold. This is
considered a normal condition. Pressing the ªO/D
OFFº switch will show that the transmission is able to
shift into and out of ªOverdrive.º
²If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
STARTING AND OPERATING 221

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Connecting trailer brakes to your vehicle's hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
²Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
mandatory for motoring safety.
²Follow the maintenance intervals in schedule ªBº for
changing the automatic transmission fluid and filter, if
you REGULARLY tow a trailer for more than 45
minutes of continuous operation.

WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter. Do
not allow petroleum base fluid to contaminate the brake
fluid as seal damage will result.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer's recommended transmis-
sion fluid, refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer's recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer's recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants, and Genuine
Parts for correct fluid type.
Fluid Level Check ± 3.7L 42RLE
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid.
MAINTAINING YOUR VEHICLE 311

To check the automatic transmission fluid level properly,
the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Apply the brakes and shift the transmission into P
(Park).
5. The fluidMUSTbe checked with the transmission in
P (Park) to be sure that the fluid level is accurate.
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
At normal operating temperature (approximately 180É F
(82É C), the fluid level is correct if it is in the HOT region(cross-hatched area) on the oil level indicator. The fluid
level indicator should be in the COLD region at 70É F (21É
C) fluid temperature.
If the fluid level is low, add sufficient fluid to bring to the
proper level. Refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type.
Fluid is added through the dipstick tube.
NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks.
312 MAINTAINING YOUR VEHICLE

Hydraulic Clutch Fluid Ð Manual Transmission
The clutch hydraulic system is a sealed maintenance free
system. In the event of leakage or other malfunction, the
system must be replaced.
Manual Transmission
Selection of Lubricant
Use only manufacturer's recommended manual trans-
mission fluid, refer to Recommended Fluids, Lubricants,
and Genuine Parts for correct fluid type.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16º (4.76 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
Frequency of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless the
lubricant has become contaminated with water. If con-
taminated with water, the fluid should be changed im-
mediately.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid leak is
evident, the transfer case fluid level can be checked by
removing the fill plug (B) located at the back of the
transfer case.

²Off-road or desert driving.
NOTE:Most vehicles are operated under the conditions
listed for Schedule ªB.º
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule ªB.º
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent, add as required.
Once a Month
²Check the tire pressure and look for unusual wear or
damage.
²Inspect the battery, and clean and tighten the terminals
as required.
