2007 DODGE GRAND CARAVAN automatic transmission

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

Once a Month
• Check tire pressure and look for unusual wear or
damage.
• Inspect the battery and clean and tighten the terminals
as required.
• Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
• Check all lights and all other electrical items for correct
operation. At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect the brake hoses.
• Inspect the CV joints and front suspension compo-
nents.
• Check the automatic transmission fluid level.
• Check the coolant level, hoses, and clamps.468 MAINTENANCE SCHEDULES
