Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear for 3.6L engine, fourth
and fifth gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following condi-
tions 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;
•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” in this section.
During cold temperature operation you may notice de-
layed upshifts, depending on engine and transmission
temperature. This feature improves the warm-up time of
the engine and transmission.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “TRANSMISSION
OVER TEMP” message may display, and the transmis-
sion may downshift out of Overdrive until the transmis-
sion cools down. After cool down, the transmission will
resume normal operation.

drops below a calibrated speed, or during acceleration,
the clutch automatically and smoothly disengages.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 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
transmission is not shifting into Overdrive when cold.
This is normal. Manually shifting (using the ERS shift
control) between 4 (direct gear) and 5/D (Overdrive
gear) positions will demonstrate that the transmission
is able to shift into and out of Overdrive. For vehicles
with 5.7L engines (which have two Overdrive gears),
the transmission may not shift into the top Overdrive
gear (normal fifth gear) until the transmission fluid
and engine coolant are warm.
•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 after starting the
engine.
ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
(3.6L Engine) – If Equipped
This system contains a single-speed (HI range only)
transfer case, which provides convenient full-time all-
wheel drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
TOW/HAUL mode (if equipped), or a lower gear range,
should be selected.
NOTE:Using the TOW/HAUL mode (if equipped) or
selecting a lower gear range (using the Electronic Range
Select (ERS) feature) while operating the vehicle under
heavy operating conditions, will improve performance
and extend transmission life by reducing excessive shift-
ing and heat buildup. This action will also provide better
engine braking. The transmission fluid and filter should be changed if
you REGULARLY tow a trailer for more than 45 minutes
of continuous operation. Refer to “Maintenance Sched-
ule” for the proper maintenance intervals.
NOTE:
Check the transmission fluid level before towing
(5.7L engine).
Electronic Speed Control – If Equipped
Do not 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.

Adding Fluid
Add fluid at the filler hole, until it runs out of the hole,
when the vehicle is in a level position.
Drain
First remove fill plug, then remove drain plug. Recom-
mended tightening torque for drain and fill plugs is 15 to
25 ft lbs (20 to 34 N·m).
CAUTION!
When installing plugs, do not overtighten. You could
damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
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 the manufacturer’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important that the transmission fluid be main-
tained 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” in “Main-
taining Your Vehicle” for further information.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check – 3.6L Engine
Regular fluid level checks are not required. For this
reason, the dipstick is omitted.
If you notice fluid loss or transmission slippage or
malfunction, have your authorized dealer check the
transmission fluid level.
