Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission
fluid level is when the engine oil is changed.
Change both the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
D In heavy city traffic where the outside temperature
regularly reaches 90
_F (32_C) or higher.
D In hilly or mountainous terrain.
D Uses such as high performance operation.
D When doing frequent trailer towing.
D Uses such as found in taxi, police or
delivery service.
If you do not use your vehicle under any of
these conditions, change the fluid and filter
every 50,000 miles (83 000 km).
