automatic transmission CHRYSLER PACIFICA 2006 1.G User Guide

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.

•If 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 — 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.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit
and/or the viscous coupling.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE: This light only shows that the parking brake is
applied. It does not show the degree of brake application.
266 STARTING AND OPERATING

•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block or chockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR 4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
Tires–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to the Tires–General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
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.

314 STARTING AND OPERATING

WARNING!
•Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot
be started this way. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has a
discharged battery, booster cables may be used to obtain a
start from another vehicle. This type of start can be danger-
ous if done improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don’t lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
•A battery generates hydrogen gas which is flammable and
explosive. Keep flame or spark away from the vent holes.
Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
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.
328 WHAT TO DO IN EMERGENCIES

All Transmissions
CAUTION!
•Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
•Always use wheel lift equipment when towing
from the front. The only other approved method
of towing is with a flat bed truck.
•Do not tow the vehicle from the rear. Damage to
the rear sheet metal, liftgate and fascia will occur.
•Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.
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.

336 MAINTAINING YOUR VEHICLE

ONBOARD DIAGNOSTIC SYSTEM — 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 “Malfunction Indicator Light.” 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 “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
340 MAINTAINING YOUR VEHICLE

CAUTION!
Do not allow petroleum base fluid to contaminate
the brake fluid, all brake seal components could be
damaged causing partial or complete brake failure.
Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses and quick connect fittings which
have unique material characteristics to provide adequate
sealing and resist attack by deteriorated gasoline.
You are urged to use only the manufacture specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service. Care should be taken in installing quick connect fittings
to insure they are properly installed and fully connected.
See your authorized dealer for service.
Automatic Transmission
The automatic transmission and differential assembly are
contained within a single housing.
All automatic transmissions are equipped with a conven-
tional filler tube and dipstick. If fluid is added, it should
be added through the dipstick hole in the case.
The dipstick is located just behind the radiator, lower
right side.
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturers recommended transmis-
sion fluid, refer to Fluids, Lubricants and Genuine Parts
MAINTAINING YOUR VEHICLE 367

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-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants and Genuine Parts for correct
fluid type.Procedure For Checking Fluid Level
The fluid level in the automatic transmission should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transmission and of the fluid.
To properly check the automatic transmission fluid level,
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.
