When to Check and Change Automatic Transmission Fluid

It is usually not necessary to check the transmission fluid level. The only reason for fluid loss is a transmission leak or overheating the transmission. If you suspect a small leak, then use the following checking procedures to check the fluid level. However, if there is a large leak, then it may be necessary to have the vehicle towed to a dealer/retailer service department and have it repaired before driving the vehicle further.

Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle’s warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on

page 7-13.

Change the fluid and filter at the intervals listed in the Maintenance Schedule. See Scheduled Maintenance on page 7-4. Be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 7-13.

How to Check Automatic Transmission Fluid

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.

Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid.

Before checking the fluid level, prepare the vehicle as follows:

1.Start the engine and park the vehicle on a level surface. Keep the engine running.

2.Apply the parking brake and place the shift lever in P (Park).
