the intervals listed inPart A: Scheduled Maintenance
Services on page 6-4, and be sure to use the
transmission uid listed inPart D: Recommended
Fluids and Lubricants on page 6-19.
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:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission uid listed in
Part D: Recommended Fluids and Lubricants on
page 6-19.
Wait at least 30 minutes before checking the
transmission uid 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.
To get the right reading, the uid should be at normal
operating temperature, which is 158°F to 176°F
(70°C to 80°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above
50°F (10°C). If it is colder than 50°F (10°C), you
may have to drive longer.
