How to Check Automatic Transaxle
Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealership
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 transaxle. Too much can mean
that some of the fluid could come out and fall
on hot engine or exhaust system parts,
starting a fire. Too little fluid could cause the
transaxle to overheat. Be sure to get an
accurate reading if you check the transaxle
fluid.
Wait at least 30 minutes before checking the
transaxle 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.
To get the right reading, the fluid 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.
