* Drain Plug: This is the most common "plug" people ask about. It's located on the bottom of the transmission case. You'll need to get under the Jeep to see it. Its exact location might vary slightly depending on the specific transmission (AX-5, NV3550, etc.), but it will always be on the bottom.
* Fill Plug: This is often located on the side of the transmission case, usually higher up than the drain plug. Again, its precise location varies by transmission type.
* Other Plugs/Sensors: There might be other smaller plugs on the transmission for various sensors or other components. These are less likely what you are looking for unless you're working on a specific component.
To find the drain and fill plugs: It's best to consult a repair manual specific to your 2001 Jeep Wrangler's transmission type. A Haynes or Chilton manual will have diagrams showing the exact locations. You can also search online for diagrams specific to your transmission (e.g., "2001 Jeep Wrangler AX-5 transmission drain and fill plug"). Looking at pictures online of similar Jeep Wranglers might also help.
