automatic transmission fluid DODGE GRAND CARAVAN 2007 Owners Manual

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
17. Washer Fluid Light
This light turns on when the washer fluid level
falls below approximately 1/4 filled. The light will
remain on until fluid is added.
18. Transmission Range Indicator
This display indicator shows the automatic transaxle gear
selection. NOTE: You must apply the brakes before shifting from
Park.
19. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for 4 minutes when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked under the hood.
20. High Beam Light
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low
beam. UNDERSTANDING YOUR INSTRUMENT PANEL 217

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.7 - Pin Connector STARTING AND OPERATING 381

• For convenience in checking the spare tire inflation,
stow with the valve stem toward the rear of the
vehicle.
• Using the jack handle, rotate the drive nut to the
right until the wheel is drawn into place against the
underside of the vehicle.
• Continue to rotate the nut until you hear the mecha-
nism click three times. It cannot be overtightened.
Push against the tire several times to be sure it is
securely in place.
13. Stow the jack and jack handle.
14. Check the tire pressure as soon as possible. Correct
pressure as required. JUMP-STARTING PROCEDURE
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 con-
verter 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 dangerous 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.
• Take care to avoid the radiator cooling fan whenever the hood
is raised. It can start anytime the ignition switch is on. You can
be hurt by the fan. WHAT TO DO IN EMERGENCIES 405

WARNING!Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
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 which have unique material charac-
teristics to provide adequate sealing and resist attack by
deteriorated gasoline.
Use only the manufacturers specified hoses in any fuel
system servicing. It is mandatory to replace all clamps
that have been loosened or removed during service. Care
should be taken in installing new clamps to insure they
are properly torqued.
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.442 MAINTAINING YOUR VEHICLE

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.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (PARK). Wipe the area
around the dipstick clean to eliminate the possibility of
dirt entering the transmission. 5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°C), which
is the normal operating temperature after the vehicle has
been driven at least 15 miles (24 km). The fluid cannot be
comfortably held between the finger tips. Cold is when
the fluid is below 80°F (27°C).
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in the
crosshatched area marked “HOT” (between the upper
two holes in the dipstick).
b. If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “COLD”.
If the fluid level indicates low, add sufficient fluid to
bring to the proper level.444 MAINTAINING YOUR VEHICLE

CAUTION!Do not overfill. Dirt and water in the transmission
can cause serious damage. To prevent dirt and water
from entering the transmission after checking or
replenishing fluid, make certain that the dipstick cap
is reseated properly.
Fluid and Filter Changes
Automatic transmission fluid should be changed on all
transmissions as follows:
Normal Usage — No change necessary
Severe Usage (fluid and filter) — Refer to Maintenance
Schedule “B” Severe Usage is defined as:
• Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is driven regularly for
more than 45 minutes of continuous operation.
NOTE: Refer to Section 8 of this manual for Mainte-
nance Schedules.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
Special Additives
Do not add any fluid additives to the transmission. The
only exception to this policy is the use of special dyes to
aid in detecting fluid leaks. The use of transmission
sealers should be avoided as they may adversely affect
seals. MAINTAINING YOUR VEHICLE 445
