Then, without shutting off the engine, follow these steps: Hot Check Procedure The fluid must be hot to ensure an accurate check. The fluid level rises as the 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. 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. Cold Check Procedure The purpose of the cold check is to determine if the transmission has enough fluid to be operated safely until a hot check can be made. The fluid level rises as fluid temperature increases. Do not fill above the COLD CHECK band if the transmission fluid is below normal operating temperatures. 1. Pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds and then pull it back out again. 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. 5-31
