Here are more specific steps on how to locate the speed sensor:
1. Park the vehicle on a level surface and turn off the engine.
2. Locate the transmission pan. It is located under the vehicle, near the rear of the engine.
3. Look for a small, cylindrical sensor with a wire harness attached to it. This is the speed sensor.
4. Disconnect the wire harness from the speed sensor.
5. Use a wrench to loosen and remove the speed sensor from the transmission.
To reinstall the speed sensor, simply follow these steps in reverse order.
