Neutral Safety Switch | Ford AOD Automatic Transmission

Make your AOD transmission swap safe and fully functional with this Neutral Safety Switch (NSS), a critical electrical component for any Ford AOD installation. Whether you’re restoring a factory-equipped AOD vehicle or converting your Early Bronco or classic Ford to an AOD, this switch ensures the transmission only starts in Park or Neutral—protecting the vehicle, the transmission, and the driver. It also controls the reverse-lamp circuit, restoring proper back-up light function when the shifter is placed in Reverse.

Pro Tip: When installing the switch during an AOD swap, make sure the shifter linkage is properly adjusted—an out-of-alignment shifter can cause no-start issues or inoperative reverse lights. This switch mounts to the factory 4-pin connector on the wiring harness. If you are swapping an AOD into your Early Bronco or other classic vehicle, make sure to pick up a 4-pin AOD connector to complete the installation.
