2004 CHRYSLER PACIFICA automatic transmission

Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ACCESSORY or ON
position.
NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four Speed Automatic Transmission
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle, may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles.
Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into sec-
ond gear. The transmission remains in second gear
despite the forward gear selected. Park (P), Reverse (R),
and Neutral (N) will continue to operate. This Reset
feature allows the vehicle to be driven to a dealer for
service without damaging the transmission.
In the event that the problem has been momentary, the
transmission can be reset to regain all forward gears.
²Stop the vehicle and shift into Park (P).
²Turn the key to OFF then restart the engine.
²Shift into the desired range and resume driving.
202 STARTING AND OPERATING

AUTOSTICK
Autostick is a driver-interactive transmission that offers
manual gear shifting capability to provide you with more
control. Autostick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Autostick Operation
The Autostick position is just below the Overdrive posi-
tion and is identified by the word ªAUTOSTICKº. When
you place the shift lever in the Autostick position, it can
be moved from side to side. Moving the lever to the left
(-) triggers a downshift and to the right (+) an upshift.
The gear position will be shown in the transmission gear
display, located in the instrument cluster.You can shift in or out of the autostick mode at any time
without taking your foot off the accelerator pedal. If you
choose the Overdrive mode, the transmission will oper-
ate automatically; shifting between the four available
gears. When you wish to engage autostick, simply move
the shift lever to the AUTOSTICK position. The transmis-
sion will remain in the current gear until an upshift or
downshift is chosen.
Move the lever back to the Overdrive position to shift out
of the Autostick mode.Autostick General Information
²
The transmission will automatically upshift from first
to second gear and from second to third gear when
engine speed reaches about 6300 RPM.
²Downshifts from third to second gear above 74 mph
(119 km/h) and from second to first gear above 41
mph (66 km/h) will be ignored.
204 STARTING AND OPERATING

²You can start out in first, second, or third gear. Shifting
into fourth gear can occur only after vehicle speed
reaches 15 mph (24 km/h).
²The transmission will automatically downshift to first
gear when coming to a stop.
²Starting out in third gear is helpful in snowy or icy
conditions.
²While in the Autostick mode, Speed Control will only
function in third or fourth gear.
Downshifting out of third gear will turn off the speed
control.
²If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
²If the system detects a problem it will disable the
Autostick mode and the transmission will return to the
automatic mode until the problem is corrected.
ALL WHEEL DRIVE Ð IF EQUIPPED
This feature provides full time, on-demand, All Wheel
Drive (AWD). The system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
STARTING AND OPERATING 205

²The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more
than 45 minutes of continuous operation. See Schedule
ªBº in section 8 of this manual for transmission fluid
change intervals.
NOTE:
²Check the automatic transmission fluid level before
towing. Fluid discoloration, or a burnt odor, shows the
need for a transmission fluid and filter change.
²For vehicles equipped with Autostick. By using the
Autostick modes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose ª4º if the desired
speed can be maintained. Choose ª3º or ª2º if needed
to maintain the desired speed.
²Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehiclespeed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.

246 STARTING AND OPERATING

1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF position for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.
4. Connect one end of a jumper cable to the positive
terminal of the discharged battery. Connect the other end
of the same cable to the positive terminal of the booster
battery.5. Connect the other cable, first to the negative terminal
of the booster battery andthen to the engine of the
vehicle with the discharged battery.Make sure you have
a good contact on the engine.
6. Start the engine in the vehicle which has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.
WHAT TO DO IN EMERGENCIES 259

If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACCESSORY position. Make certain the
transmission remains in NEUTRAL.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing with out the ignition key is
with a flat bed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Flat towing of vehicles equipped with an automatic
transmission, is only permitted within the limitations
described in this section.
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE WITH A TOW DOLLEY
The manufacturedoes not recommendthat you tow an
All-Wheel Drive (AWD) or front wheel drive vehicle on a
tow dolley. Vehicle damage may occur.

266 MAINTAINING YOUR VEHICLE

ONBOARD DIAGNOSTIC SYSTEM Ð OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur. Im-
mediate service is required.
