Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Check the fluid in the transaxle and differential every
30,000 miles (50 000 km). Change the fluid every
60,000 miles (100 000 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.
See Part A: Scheduled Maintenance Services on
page 6-4.
How to Check
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
your 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 your
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 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’s colder than 50°F (10°C), you may have to
drive longer.
