If the fluid color is very dark or black and has a burnt odor, inspect the fluid for excessive metal particles or other debris which may indicate
transmission damage. Refer to Road Test   (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Initial
Inspection and Diagnostic Overview/6T70/6T75 - Automatic Transmission) 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   (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Symptom Related
Diagnostic Procedures/6T70/6T75 - Automatic Transmission/Engine Coolant/Water in Transmission).
