Consistency of Readings
Always check the fluid level at least twice using the
procedures described. Consistency (repeatable
readings) is important to maintaining proper fluid level.
If fluid is added, it may take 15 minutes or longer to
obtain an accurate reading because of residual
fluid draining down the dipstick tube. If inconsistent
readings persist, check the transmission breather to
be sure it is clean and not clogged. If readings are
still inconsistent, contact your dealer/retailer.

When to Check and Change Automatic
Transmission Fluid
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change the fluid and filter at the intervals listed in
Additional Required Services on page 6-7 , and be sure
to use the transmission fluid listed in Recommended
Fluids and Lubricants on page 6-15 .
How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult, you may
choose to have this done at the dealer/retailer 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.
Too little fluid could cause the transmission to
overheat. 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:
•
When outside temperatures are above 90°F (32°C).
•
At high speed for quite a while.
•
In heavy traffic — especially in hot weather.
•
While pulling a trailer.
