The park / neutral position switch is a vital safety device fitted to Porsche models equipped with automatic transmissions. Over time, internal electrical contacts can wear, contamination can affect operation, or the switch can become damaged or misaligned, leading to intermittent starting issues or incorrect gear position recognition. Replacing the switch with a Genuine Porsche component restores factory-correct functionality, reliability, and safety, making it ideal for maintenance, repairs, and concours-standard restoration projects.  

What This Product Does:

• Detects when the transmission is in Park or Neutral.
• Allows the engine to start only in the correct selector positions.
• Prevents accidental engine starting while a drive gear is engaged.
• Sends accurate gear position signals to the vehicle's electrical systems.
• Supports safe and reliable automatic transmission operation.
• Replaces worn or faulty original switches.
• Provides genuine Porsche fit, performance, and reliability.

Symptoms Of Wear Or Failure:

• Engine will not start in Park or Neutral.
• Intermittent starting problems.
• Vehicle starts while in gear.
• Incorrect gear position indication.
• Transmission warning lights or fault codes.
• Inconsistent operation of the gear selector.
• Worn, damaged, or contaminated switch contacts.
• Age-related deterioration of the original component.

Why Replacement Matters:

• The park / neutral position switch is a critical safety component that ensures the engine can only be started when the automatic transmission is in Park or Neutral. A faulty switch can cause intermittent no-start conditions, inaccurate gear position signals, or, in severe cases, allow the engine to start while a drive gear is selected, creating a potential safety hazard.
• Replacing a worn or defective switch restores the correct operation of the starting interlock system, improves transmission signal accuracy, and maintains the safety and reliability of your Porsche. Manufactured to Porsche's original equipment specification and supplied under part number 311927147B, this Genuine Porsche component delivers the precise fit, durability, and dependable performance expected from factory-original parts.
