Vehicle Care 10-15 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 or the procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 13-11. Change the fluid at the intervals listed in Maintenance Schedule on page 11-2, and be sure to use the fluid listed in Recommended Fluids and Lubricants on page 11-12.
