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 the fluid and filter at the intervals listed in Additional Required Services , and be sure to use the transaxle fluid listed in Recommended Fluids and Lubricants .
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.
Checking the Fluid Level
Prepare your vehicle as follows:
| • | Park your vehicle on a level place. Keep the engine running. |
| • | With the parking brake applied, place the shift lever in PARK (P). |
| • | With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). |
| • | Let the engine run at idle for three to five minutes. |

The transaxle fluid dipstick handle is the black loop near the rear of the engine compartment, toward the center. See Engine Compartment Overview for more information on location.
Then, without shutting off the engine, follow these steps:
- Pull out the dipstick and wipe it with a clean rag or paper towel.
- Push it back in all the way, wait three seconds and then pull it back out again.
- If the fluid level is in the acceptable range, push the dipstick back in all the way.

Check both sides of the dipstick, and read the lower level. The fluid level must be in the cross-hatched area.
How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Recommended Fluids and Lubricants .
If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick.
- Pull out the dipstick.
- Using a long-neck funnel, add enough fluid at the dipstick hole to bring it to the proper level.
- After adding fluid, recheck the fluid level as described under "How to Check Automatic Transaxle Fluid," earlier in this section.
- When the correct fluid level is obtained, push the dipstick back in all the way.
It does not take much fluid, generally less than one pint (0.5 L). Do not overfill.
Notice: Use of the incorrect automatic transaxle fluid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transaxle fluid listed in Recommended Fluids and Lubricants .
