* Automatic Transmission: The speed sensor is typically located on the side of the transmission case. It's a relatively small sensor, often with a single wire connector. You'll likely need to get under the vehicle to locate it. A shop manual specific to your year and transmission is highly recommended.
* Manual Transmission: With a manual transmission, the speed sensor is usually part of the vehicle speed sensor (VSS) which is often located on the output shaft of the transmission near the rear differential or driveshaft. Again, a shop manual is crucial for precise location.
To find the exact location:
1. Consult a repair manual: A Haynes or Chilton manual for your specific year and model Ford E-350 is your best bet. These manuals will have diagrams and detailed instructions.
2. Use a parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) let you look up parts diagrams by vehicle year, make, and model. Finding the speed sensor in the diagram will show you its approximate location.
3. Check online forums: Searching online forums dedicated to Ford E-350s might yield answers from other owners who've worked on the same system.
Without knowing your transmission type, any location I give you could be incorrect and lead to wasted time. Always use a reliable repair manual for accurate information.
