How to Check Because this operation can be a little difficult, you may choose to have this done at yourChevrolet 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. Wait at least30 minutes before checking the transaxle fluid levelif 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. 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 parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transaxle fluid. _ _ - To get the right reading, the fluid should be at normal operating temperature, whichis 180°F to 200°F (82°C to 93 "C). Get the vehicle warmed up by driving about 15 miles (24 k ) m when outsidetemperatures are above 50°F (10°C). If it's colder than50°F (lO"C), you may have to drive longer. 6-19
