If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.

For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level. Refer to "Fluids
And Lubricants" in "Technical Specifications" for
further information. This inspection should be
made with the vehicle in a level position.
The fluid level should be even with the bottom of
the fill hole (within 1/4 inch (6.4 mm) of edge of
hole) for the FDU215 HD front axle and C235FE
rear axle.
Lubricant Selection
Refer to "Fluids And Lubricants" in "Technical
Specification" for further information.
NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differ-
ential components. Operation of the vehicle in
water, as may be encountered in some off-highway
types of service, will require draining and refilling
the axle to avoid damage.
Limited-Slip Differentials
If equipped with a Limited Slip Differential it will
require that 5 oz. (148 ml) of Mopar Limited Slip
Additive be added to the gear lubricant. Refer to
D
"Fluids And Lubricants" in "Technical
RIVING
Specification" for further information. The Mopar
Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an
axle equipped with a Limited Slip Differential.
SERVICING AND MAINTENANCE
NOTE:
When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the
Limited Slip Additive should be added before the
gear lubricant is added to insure proper additive
fill.
Drain And Refill
Refer to the "Maintenance Plan" in this chapter for
the proper maintenance intervals.

Selection Of Lubricant
Use only the manufacturer's recommended fluid.
Refer to "Fluids And Lubricants" in "Technical
Specifications" for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of
the filler plug hole (or at least within 1/8 inch of the
bottom) with the vehicle in a level position.
Drain And Refill
Refer to the "Maintenance Plan" in this chapter for
the proper maintenance intervals.
