To find it, you'll likely need to:
1. Consult your repair manual: A repair manual specific to your year and model Silverado will provide diagrams and detailed instructions for locating the speed sensor. This is the most reliable method.
2. Search online for diagrams: Use a search engine like Google, Bing, or DuckDuckGo with search terms like "2000 Chevy Silverado speed sensor location [transmission type]" (replacing "[transmission type]" with "automatic" or "manual"). Look for images and diagrams.
3. Visually inspect the transmission: This is the least reliable method but may work. The sensor is usually a small, relatively easy-to-access component on the side or back of the transmission. It will likely have a wire harness connected to it. Be cautious when working near the transmission.
Important Note: Before attempting to locate or replace the sensor, disconnect the negative battery terminal to prevent electrical shorts. If you are not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
