2006 JEEP LIBERTY automatic transmission fluid

CAUTION!
•Never press on the accelerator pedal with the
engine running, vehicle in gear, and the brakes
applied. Always apply the brakes when stopped
on a incline. Failure to follow these instructions
can cause overheating and damage to the trans-
mission.
•When “rocking” a stuck vehicle by moving be-
tween “First” and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
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:
•The torque converter clutch (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
232 STARTING AND OPERATING

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals. NOTE:
Check the automatic transmission fluid level
before towing.
Towing Tips — O/D OFF (If Equipped)
To reduce potential for automatic transmission overheat-
ing, press the “O/D OFF” button when driving in hilly
areas or shift the transmission to Drive position 2 on
more severe grades. Refer to “Transmission Shifting” in
this section.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

312 MAINTAINING YOUR VEHICLE

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 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
Fluids, Lubricants, and Genuine Parts for correct
fluid type.
Fluid Level Check – 3.7L Gasoline Engine (42RLE)
and 2.8L Diesel Engine (545RFE)
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.
340 MAINTAINING YOUR VEHICLE

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 fluid MUSTbe 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 180° F
(82° 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 70° F (21°
C) fluid temperature.
If the fluid level is low, add sufficient fluid to bring to the
proper level. Refer to 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.
