Dorman Neutral Safety Switch 924-435 — Direct-fit OE replacement with durable construction

The Dorman 924-435 Neutral Safety Switch is a direct-fit replacement that restores proper gear-position signaling so your vehicle’s ignition and transmission control circuits behave as intended.

If a neutral safety switch has failed or been lost due to internal damage, the vehicle’s PCM, starter circuit, or ignition system may no longer receive a clear signal about whether a gear is engaged. The Dorman 924-435 is engineered to match the original equipment’s fit and function on specified applications, giving you a reliable way to re-establish that critical gear-position communication without modifying wiring or mounting points.

How does this switch restore safe starting and shifting?

Replacing a faulty switch with the Dorman 924-435 reintroduces the intended electrical interlock between the transmission selector and the starter/ignition circuitry. That enables the PCM and starter relay to receive accurate gear-position information so the vehicle only starts in safe conditions.

• Direct-fit design aligns with OE mounting and electrical connectors
• Signals neutral/park or other engaged gears to the vehicle control modules
• Prevents starter engagement in incorrect gear positions

Will the Dorman 924-435 fit my vehicle without modifications?

How do I install the replacement safely and verify it works?

Installation typically requires basic hand tools and a short disconnection of the battery. After mounting and connecting the replacement, verify correct operation by confirming the vehicle starts only in neutral/park and that gear-position signals register on the dash or diagnostic scan tool.

• Disconnect battery before removing the old switch to avoid shorts
• Match connector and mounting orientation to the OE component
• Test starting and gear-indicator behavior after installation
