Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) Mopar Limited Slip
Additive be added to the gear lubricant. Refer to “Fluids,
Lubricants, And Genuine Parts” in “Maintaining Your
Vehicle” 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.
2500/3500 Model axles DO NOT REQUIRE any limited
slip oil additive (friction modifiers).
NOTE: When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the Lim-
ited Slip Additive should be added before the gear lubri-
cant is added to insure proper additive fill.
Transfer Case

Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.

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 with the vehicle in a level position.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in this section
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid. No chemical flushes should be used in any
transmission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
ers recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And Genu-
ine Parts” in this section for fluid specifications.
