3. Check the fluid level reading. Repeat the check procedure to verify the reading. 4. If the fluid level is within the COLD CHECK band, the transmission may be operated until the fluid is hot enough to perform a hot check. If the fluid level is not within the COLD CHECK band, add or drain fluid as necessary to bring the level into the middle of the COLD CHECK band. 5. Perform a hot check at the first opportunity after the normal operating temperature of 160°F (71°C) to 200°F (93°C) is reached. 6. If the fluid level is in the acceptable range, push the dipstick back in all the way. 3. Push it back in all the way, wait three seconds and then pull it back out again. Repeat the check procedure to verify the reading. 4. Safe operating level is within the HOT RUN band on the dipstick. The width of the HOT RUN band represents approximately 1.06 quart (1.0 liter) of fluid at normal operating temperature. 5. If the fluid level is not within the HOT RUN band, add or drain fluid as necessary to bring the fluid level to within the HOT RUN band. 6. If the fluid level is in the acceptable range, push the dipstick back in all the way. Hot Check Procedure The fluid must be hot to ensure an accurate check. The fluid level rises as temperature increases. 1. Operate the transmission in DRIVE (D) range until the normal operating temperature of 160°F (71°C) to 200°F (93°C) is reached. 2. Pull out the dipstick and wipe it with a clean rag or paper towel. Consistency of Readings Always check the fluid level at least twice using the procedures described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If inconsistent readings persist, check the transmission breather to be sure it is clean and unclogged. If readings are still inconsistent, contact your dealer. 5-32
