To assess the transmission fluid condition, you should:
* Check the fluid color and condition: A qualified mechanic can access the fluid through a drain plug or other access point. The color and clarity of the fluid indicate its condition. Dark brown or burnt smelling fluid suggests it needs changing. However, simply inspecting the color doesn't tell you about the level.
* Have a professional service performed: The best way to determine if a transmission fluid service is needed is to take your Grand Caravan to a qualified mechanic or transmission specialist. They have the proper equipment and expertise to properly diagnose any transmission issues, which may or may not include a fluid change and/or level check.
Attempting to check the fluid level yourself on this type of transmission is not recommended and could lead to damage. There's no accurate method to do so without specialized equipment. Rely on professional assessment for your transmission's health.
