How to service and repair the Neutral Safety Switch on Chevrolet Lumina?

First service the transmission position switch/sensor by engaging the parking brake and wheel blockers and setting the vehicle at neutral. Start by removing three parts: the throttle body air inlet duct, automatic transaxle range selector cable, and wiring harness connectors. To access the pnp switch you need to remove several components including automatic transaxle range selector lever and pnp switch mounting bolts. Verify that the pnp switch gets installed when the shift shaft points toward neutral since the new pnp switch uses this position for assembly. If the bolt holes do not align, verify the shaft's position. Mount the pnp switch onto its base following the flat alignment across the shift gear with the pnp switch mounting bolts tightened to 25 nm (18 ft. Lbs.). Install both the automatic transaxle range selector lever and wiring harness connectors and the automatic transaxle range selector cable. Confirm engine start-up occurs exclusively during park or neutral position enactments after the installation. To start the engine only in park or neutral check the pnp switch for correct positioning because any other starting position could indicate a problem with the shifter or automatic transaxle range selector cable. To finish reinstall the throttle body air inlet duct before you take away the wheel blocks and switch off the parking brake.
