Automatic Transmission Fluid

How to Check
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to your dealer
service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at your dealer service
department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, see Service
Publications Ordering Information on page 7-10 .
Notice: We recommend you use only fluid labeled
®
DEXRON -III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON
not covered by your new vehicle warranty.

Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•
In hilly or mountainous terrain.
•
High performance operation.
If you do not use your vehicle under one of these
conditions, change the fluid and filter every
100,000 miles (166 000 km).
See Scheduled Maintenance on page 6-4 for the proper
service intervals for the transmission fluid and filter.

Manual Transmission Fluid

When to Check

changed. However, the fluid in your manual transmission
doesn't require changing.
