Level Checking Procedure

  1. Park the vehicle on a level surface, apply the parking brake and place the shift lever in PARK (P).
  2. Start the engine.
  3. Depress the brake pedal and move the shift lever through each gear range, pausing for about 3 seconds in each range. Then move the shift lever back to PARK (P).
  4. Allow the engine to idle 500-800 RPM for at least 1 minute. Release the brake pedal.
  5. Keep the engine running and observe the transmission fluid temperature (TFT) using the Driver Information Center or a scan tool.
    NOTE: If the fluid temperature is below the specified range, perform the following procedure to raise the fluid temperature to the specified range.
  6. If the TFT reading is not within the required temperature ranges, allow the vehicle to cool, or operate the vehicle until the appropriate TFT is reached.

    Drive the vehicle in second gear until the fluid temperature is within the specified range.

    NOTE: Check the transmission fluid level when the TFT is between 180 °F and 200 °F (82 °C and 93 °C). The fluid level rises as fluid temperature increases, so it is important to ensure the transmission fluid temperature is within range.
  7. Remove the dipstick and wipe it with a clean rag or paper towel.
  8. Inspect the fluid color. The fluid should be red or dark brown.
    • If the fluid color is very dark or black and has a burnt odor, inspect the fluid for excessive metal particles or other debris. A small amount of "friction" material is a "normal" condition. If large pieces and/or metal particles are noted in the fluid, flush the oil cooler and cooler lines and overhaul the transmission. If there are no signs of transmission internal damage noted, replace the fluid, repair the oil cooler, and flush the cooler lines.
    • Fluid that is cloudy or milky or appears to be contaminated with water indicates engine coolant or water contamination. Refer to ENGINE COOLANT/WATER IN TRANSMISSION .
  9. Install the dipstick and tighten. Wait three seconds and then remove it again.
    NOTE: Always check the fluid level at least twice. Consistent readings are important to maintaining proper fluid level. If inconsistent readings are noted, inspect the transmission vent assembly to ensure it is clean and unclogged.
  10. Install and remove the dipstick again to verify the reading.
  11. If the fluid level is not within the crosshatch band, and the transmission temperature is between 180 °F and 200 °F (82 °C and 93 °C), add or drain fluid as necessary to bring the level into the crosshatch band. If the fluid level is low, add only enough fluid to bring the level into the crosshatch band.
    NOTE: Do not add more than one pint (0.5 L) at a time without rechecking the level. Once the oil is on the dipstick bullet, it will not take much more fluid to raise the fluid level into the crosshatch band. Do not overfill. Also, if the fluid level is low, inspect the transmission for leaks. Refer to FLUID LEAK DIAGNOSIS .
  12. If the fluid level is in the acceptable range, install the dipstick.
  13. If the fluid was changed, reset the transmission oil life monitor if applicable.
