You need to consult your owner's manual. This is the definitive source for the correct fluids and specifications for your specific vehicle's year and configuration. The manual will specify the type and weight of oil for:
* Transmission: This will likely be an ATF (Automatic Transmission Fluid) of a specific type recommended by Dodge.
* Transfer Case: This will usually be a specific type of gear oil.
* Front and Rear Differentials: These will also require a specific type and weight of gear oil, potentially different for the front and rear.
Using the incorrect fluid can damage your components and void your warranty (if applicable). Don't rely on general advice; always check your owner's manual.
