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:

DIn heavy city traffic where the outside temperature regularly reaches 90_F (32_C) or higher.

DIn hilly or mountainous terrain.

DWhen doing frequent trailer towing.

DUses 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).

See ªScheduled Maintenance Servicesº in the Index.

How to Check

Because this operation can be a little difficult, you may choose to have this done at the dealership service department.

If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.

NOTICE:

Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.

Wait at least 30 minutes before checking the transmission fluid level if you have been driving:

DWhen outside temperatures are above 90_F (32_C).

DAt high speed for quite a while.

DIn heavy traffic --especially in hot weather.

DWhile pulling a trailer.
