Automatic Transaxle Fluid

When to Check and Change Automatic
Transaxle Fluid
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher
•
In hilly or mountainous terrain
•
When doing frequent trailer towing
•
Uses such as found in taxi, police or delivery
service
If you do not use your vehicle under any of these
conditions, change the fluid and filter at 100,000 miles
(166 000 km). See Scheduled Maintenance on page 6-4
for more information.

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 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.
