To find it:
1. Get under the truck safely: Use jack stands, never rely on a jack alone.
2. Locate the transmission pan: This is the large, flat metal pan underneath the transmission. It's usually fairly easy to identify.
3. Look closely at the bottom of the pan: The drain plug will be a bolt, usually somewhat towards the back (rear) of the pan. It might be magnetic to catch metal shavings.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 2000 Ford Ranger's year and transmission type will provide a diagram showing the exact location. This is the most reliable method.
* Safety First: Always use safety precautions when working under a vehicle.
* Transmission Fluid Type: Be sure to use the correct type of automatic transmission fluid (ATF) specified for your Ranger.
Don't assume you'll find it without looking. A quick visual inspection is essential to avoid damaging anything nearby.
