Q: Where is the neutral safety switch located on a 2005 Chevy impala

The switch is mounted on the top of the transmission case and is visible as you look down into the right rear portion of the engine compartment (as you stand facing the front grille). It will be roughly below the brake master cylinder. You will see the switch held to the transmission case by two bolts and you will clearly see the transmission range selector cable (black) attached to a 3 inch (roughly) long lever that is held on by a nut to a shaft that runs through the switch. If you need assistance with regard to this component, please request service via YourMechanic’s neutral start safety switch service request page.
