•
Automatic transmission fluid change (normal
service). SeeAutomatic Transmission Fluid
(4-Speed Transmission) on page 6-21orAutomatic
Transmission Fluid (6-Speed Transmission) on
page 6-24.
•All-wheel drive only: Transfer case fluid change
(normal service). Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free
of debris. During any maintenance, if a power
washer is used to clean mud and dirt from the
underbody, care should be taken to not directly
spray the transfer case output seals. High pressure
water can overcome the seals and contaminate
the transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.
