To find it, you'll need to:
1. Identify your transmission type: This information might be on a sticker under the hood or in your owner's manual. Knowing the transmission type will greatly narrow down the possibilities.
2. Consult a repair manual specific to your Jeep Wrangler's year and transmission: A Haynes or Chilton manual (or a digital equivalent) will have diagrams showing the location of the fill and drain plugs. These manuals are invaluable for this kind of task.
3. Look closely at the transmission case: The fill plug is usually a bolt or plug on the side or top of the transmission case. It's often smaller than the drain plug. It might be slightly recessed and may have a slightly different head shape than other bolts in the area.
Important Note: Before attempting any work on your transmission, make sure the vehicle is properly supported, using jack stands, and that you have the correct tools. Incorrectly filling your transmission can cause significant damage. If you're not comfortable doing this yourself, take it to a qualified mechanic.
