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:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
When doing frequent trailer towing.
0 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).
