A good time to check your automatic transaxle fluid is when the engine oil is changed.

Change both the fluid and filter every 30,000 miles (50 000 km):

How to Check:

Because this operation can be a little difficult, you may choose to have this done at a Saturn retail service facility.

If you do it yourself, be sure to follow all the instructions here, or you can get a false reading on the dipstick.

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, 190°F to 200°F (88°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). It it's colder than 50°F (10°C), you may have to drive longer.
