CAUTION!
Be aware that if the fluid temperature is below
10°C (50°F) it may not register on the dipstick.
Do not add fluid until the temperature is elevated
enough to produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the trans-
mission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
It is normal for the dipstick cap to spring back
slightly from its fully seated position, as long as its
seal remains engaged in the dipstick tube.
Fluid Level Check – 2.7L Diesel Engines
The fluid level is set at the factory. The dipstick
tube is sealed and should not be tampered with.
No transmission fluid level dipstick is provided.
Your authorized dealer has the proper tools to
ensure that the fluid level is set properly.
Automatic Transmission Fluid and Filter
Change
To obtain best performance and long life for
automatic transmissions, the manufacturer rec-
ommends that they be given regular maintenance
service by an authorized dealer or service center.
It is important that the transmission be adjusted
periodically, the fluid maintained at the correct
level, and that it be drained and refilled as speci-
fied.
CAUTION!
Never overfill the automatic transmission.
Foaming and loss of fluid through the vent or
filler tube, and malfunction, may result.
Special Additives
The manufacturer recommends against the addi-
tion of any additives to the transmission. Excep-
tion to this policy is the use of special dyes to aid
in detecting fluid leaks.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid
leak is found, the transfer case fluid level can be
checked by removing the filler plug located on the
back side of the transfer case. The fluid level
should be at the bottom edge of the filler plug hole
when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole until it runs out of the
hole when the vehicle is in a level position.
Draining Fluid
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and fill
plugs is 20–34 N·m (15–25 ft. lbs.).
CAUTION!
When replacing plugs, do not overtighten. You
could damage them and cause them to leak.
Selection of Lubricant
Use only manufacturer's recommended fluid, refer
to Recommended Fluids, Lubricants, and Genu-
ine Parts for correct fluid type.
Front/Rear Axle Fluid
Fluid Level Check
Lubricant should be 13mm (1/2") below the oil fill
hole.
Adding Fluid
Add lubricant only at the fill hole and only to the
level specified above.
Selection of Lubricant
Use only manufacturer's recommended fluid, refer
to Recommended Fluids, Lubricants, and Genu-
ine Parts for correct fluid type.
