Final Level Checking Procedure

WARNING: This page is about a different variant/trim than selected.
  1. Start the engine.
    NOTE: You may have to open the hood to maintain engine operation.
  2. Allow the engine to idle in Park (P).
  3. Keep the engine running and observe the transmission fluid temperature using the scan tool.
    NOTE: If the transmission fluid temperature reading is not at the required temperature, allow the vehicle to cool or operate the vehicle until the appropriate range is reached. If the fluid temperature is below the specified range, driving the vehicle will raise the fluid temperature to the specification quicker than engine idling.
  4. When the transmission fluid temperature is in the 45 - 55°C (113 - 131°F) range, move the shift lever through Park (P), Neutral (N) and Drive (D) 2 times and back to Park (P).
  5. Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range.
  6. While the vehicle is idling, remove the fluid level hole plug (2). Allow any fluid to drain.

  7. 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. Refer to Road Test  to verify transmission operation. Change the transmission fluid if no other conditions are found.
    • 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 .
  8. Inspect for external leaks. Refer to Fluid Leak Diagnosis 
  9. If the fluid was changed, reset the transmission oil life monitor if applicable.
