Transfer case fluid change
(severe service) for vehicles
mainly driven in heavy city traffic
in hot weather, in hilly or

frequently towing a trailer,
or used for taxi, police,
or delivery service. During any
maintenance, if a power washer
is used to clean mud and dirt
from the underbody, care should
