Automatic Transmission Fluid

How to Check Automatic Transmission Fluid

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.

The procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information .

Change the fluid and filter at the intervals listed in Scheduled Maintenance , and be sure to use the fluid listed in Recommended Fluids and Lubricants .
