* Automatic Transmission: The fill location is usually on the side of the transmission, often with a dipstick. This dipstick has markings to indicate the correct fluid level. You'll need to consult your owner's manual for the precise location as it varies slightly depending on the specific transmission type fitted to your Ranger.
* Manual Transmission: Manual transmissions on the 2000 Ford Ranger generally do *not* have a separate fill hole. The transmission fluid is usually checked and topped off through the fill plug on the side of the transmission, often using the same plug as the drain plug, and checked via the transmission level. Again, consult your owner's manual for the exact location and procedure.
In short: Your owner's manual is the definitive source for locating the transmission fluid fill point on your specific 2000 Ford Ranger. Without knowing whether your Ranger has an automatic or manual transmission, a precise answer isn't possible.
