Severe Usage is defined as:
•Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle 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.
All Wheel Drive (AWD) — If Equipped
Under normal operating conditions, periodic fluid level
checks and lubricant changes for the Power Transfer
Unit, Overrunning Clutch and Rear Carrier, are not
required. However when the vehicle is serviced for other
reasons, the exterior surface of these components should
be inspected for evidence of fluid leaks. Confirmed leaks
should be repaired as soon as possible.
Power Transfer Unit
The fill plug is located on the side of the power transfer
unit housing. The fluid should be maintained at a level
even with the bottom of the fill plug hole when the
vehicle is parked on a level surface. If it becomes neces-
sary to add or replace the fluid, use only the manufac-
turers recommended fluid, refer to Fluids, Lubricants
and Genuine Parts for correct fluid type.
