2007 CHRYSLER PACIFICA transmission

Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Depress the
brake pedal before shifting into any driving gear.
Normal Starting (Above 32°F / 0°C)
1. Do not depress the accelerator.
2. Turn and hold the ignition key in the START position
and release when engine starts.
3. If engine does not start after 3 seconds, depress the
accelerator lightly (while still cranking the engine).
4. If engine does not start after 15 seconds, turn the
ignition key off.
5. Wait 10 to 15 seconds, and repeat steps 1 — 5 shown
above.NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P).
Extremely Cold Weather Starting (Below
20°F /
–29°C)
Follow the same instructions in the “Normal Starting
Process” as shown above.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
High Altitude Starting (Above 4,000 ft. / 1 219 m)
Follow the same instructions in the “Normal Starting
Process” as shown above.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
270 STARTING AND OPERATING

WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ACCESSORY or ON position. Always
depress thebrake pedal first,before moving the gear
selector out of PARK.
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.
•Stop the vehicle and shift into Park (P).
•Turn the key to OFF then restart the engine.
•Shift into the desired range and resume driving.NOTE:Even if the transmission can be reset, it is
recommended that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
“P” Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion.
Apply parking brake when leaving vehicle in this range.
272 STARTING AND OPERATING

“N” Neutral
Engine may be started in this range.
“D” Overdrive
To be used for most city and highway driving, it provides
smoothest upshifts and downshifts and best fuel
economy. When frequent transmission shifting occurs
while using the “D” Overdrive position, such as when
operating the vehicle under heavy loading conditions,
(i.e. in hilly terrain, traveling into strong head winds or
while towing heavy trailers), use the AutoStick mode and
select the “3” range.
NOTE:Using the “3” range in the AutoStick mode
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.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 “AUTOSTICK”. 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.
274 STARTING AND OPERATING

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
•
The transmission will automatically upshift from first
to second gear and from second to third gear when
engine speed reaches about 6300 RPM.
•Downshifts 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.
•You 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).
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in third gear is helpful in snowy or icy
conditions.
•While 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.
•If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
