When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission fluid
level is when the engine oil is changed.
Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 73
, and be sure
to use the transmission fluid listed in Recommended
Fluids and Lubricants on page 79.
How to Check Automatic Transmission
Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealer 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 the
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 checking the
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
.
When outside temperatures are above
32°C (90°F).
.
At high speed for quite a while.
.
In heavy traffic especially in hot weather.
.
While pulling a trailer.
To get the right reading, the fluid should be
at normal operating temperature, which is
82°C to 93°C (180°F to 200°F).
Get the vehicle warmed up by driving about
24 km (15 miles) when outside temperatures are
above 10°C (50°F). If it is colder than 10°C (50°F),
you may have to drive longer.
