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. How-
ever, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
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
page 255. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE:
No chemical flushes should be used in any transmis-
sion; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder
page 255.
FRONT/REAR AXLE FLUID
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.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Selection Of Lubricant
Use only the manufacturer's recommended fluid
page 255.
TRANSFER CASE
Fluid Level Check
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the transfer case assembly
should be inspected. If oil leakage is suspected inspect
the fluid level.
Adding Fluid
With the vehicle in a level position, fill the transfer case
to bottom edge of fill plug opening.
Drain
First remove fill plug, then remove drain plug. Recom-
mended tightening torque for drain and fill plugs is
15 to 25 ft lbs (20 to 34 N·m).
CAUTION!
When installing plugs, do not overtighten. You could
damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer's recommended fluid
