Fluid Condition Check

  1. Check the fluid level.
  2. Observe the color and the odor. The color under normal circumstances should be dark reddish, not brown or black.
  3. Hold the fluid level indicator over a white facial tissue and allow the fluid to drip onto the facial tissue and examine the stain.
  4. If evidence of solid material is found, the oil pan should be removed for further inspection.
  5. If the stain is a foamy pink color, this may indicate coolant in the transmission. The engine cooling system should also be inspected at this time.
  6. If fluid contamination or transmission failure is confirmed by the sediment in the bottom of the oil pan, the transmission may need to be replaced and torque converter and cooling lines flushed.
  7. Perform diagnostic checks and adjustments; see SYMPTOM TROUBLESHOOTING CHART - AUTOMATIC TRANSMISSION  .
