* Check the Vehicle Identification Number (VIN): The VIN contains encoded information about your vehicle's specifications, including the transmission. You can decode your VIN using online VIN decoders (many are free) or by contacting a Ford dealership. This is the most reliable method.
* Look at the Transmission Identification Tag: The transmission itself usually has a tag or sticker affixed to it with an identifying number. This requires accessing the transmission, which might involve going under the vehicle. The tag's location varies slightly depending on the transmission type and specific Expedition model.
* Check Your Owner's Manual: Your owner's manual should list the transmission type for your specific vehicle configuration (engine size, trim level, etc.).
* Look for markings on the transmission case: Sometimes, markings (letters and/or numbers) on the transmission case itself can provide clues. This requires visual inspection from underneath the vehicle. However, it's not always reliable for positive identification.
* Consult a Ford Dealership or Mechanic: A Ford dealership or experienced mechanic can easily identify the transmission type by inspecting your vehicle. They might use the VIN or a visual inspection.
The 2001 Ford Expedition most commonly used either a 4R70W four-speed automatic or a 4R100 four-speed automatic, but verifying the specific transmission using the methods above is crucial for accuracy.
