To find the correct fluid, you must check your owner's manual. It will specify the exact type of fluid recommended for your truck's transmission. The manual will often list the fluid by its ATF designation (e.g., ATF+4, Mercon V, etc.).
If you don't have the owner's manual, you can try:
* Checking the transmission dipstick: Sometimes the recommended fluid type is printed on the dipstick itself.
* Looking for a sticker under the hood: There might be a sticker on the engine bay indicating the recommended fluids.
* Using your VIN number: A Dodge dealership or parts store can use your Vehicle Identification Number (VIN) to identify the transmission and the correct fluid.
Using the wrong transmission fluid can severely damage your transmission. Don't guess – find the correct information before adding any fluid.
