When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle fluid
level is when the engine oil is changed.
Change the fluid and filter at the intervals listed
in Additional Required Services on page 464,
and be sure to use the transaxle fluid listed
in Recommended Fluids and Lubricants
on page 470.
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.
