Automatic Transaxle Fluid
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 6-6, and be sure
to use the transaxle fluid listed in Recommended
Fluids and Lubricants on page 6-12.
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.
• While pulling a trailer.
To get the right reading, the fluid should be at
normal operating temperature, which is 180°F to
200°F (82°C to 93°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.
