Where can you find the speed sensor location on a Buick Riviera 96?

The speed sensor on a 1996 Buick Riviera is most likely located on the transmission. There isn't a single universally agreed upon location, as it can vary slightly depending on the specific transmission type (automatic or manual - though it's highly probable it's an automatic in a 1996 Riviera).

To find it, you'll need to:

1. Consult a repair manual: A Haynes or Chilton repair manual specific to a 1996 Buick Riviera will have diagrams showing the exact location of the vehicle speed sensor (VSS). This is the most reliable method.

2. Look near the transmission: Focus your search on the area where the transmission output shaft connects to the differential. The sensor is usually mounted on the transmission case near this connection point. It might be on the side, top, or even the bottom, often with a wiring harness attached.

3. Inspect the wiring harness: Follow the wiring harness from the instrument cluster or PCM (Powertrain Control Module) towards the transmission. The sensor will be at the end of that wire.

4. Use an online parts diagram: Some auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to look up parts diagrams for your specific vehicle. These diagrams often show the location of sensors.

Important Note: Before attempting to locate or access the speed sensor, ensure the vehicle is turned off, the key is removed, and the parking brake is engaged. Working on a car's transmission area requires some mechanical knowledge and tools. If you are not comfortable doing this yourself, it's best to take your vehicle to a qualified mechanic.
