Oldsmobile 1994255 Switch Assembly, Automatic Transmission Neutral Start

Firmly apply both the parking brake and the regular brakes. If the engine starts, be ready to turn off the ignition promptly. Take these precautions because the vehicle could move without warning and possibly cause personal injury or property damage. On automatic transaxle vehicles, try to start the engine in each gear. The engine should start only in Park or Neutral due to the Neutral Safety Switch. On manual transaxle vehicles, place the shift lever in Neutral, push the clutch halfway and try to start. The engine should start only when the clutch is fully depressed because of the Neutral Safety Switch.

This switch ensures the vehicle only starts when the clutch pedal is fully depressed. Mounted on the clutch pedal bracket, it's activated by a plastic shaft. To remove, disconnect the electrical coupler and the switch actuating shaft. For installation, attach the switch to the bracket, align the actuating shaft with the pedal arm hole, and connect the electrical coupler. No adjustments are needed as the switch is self-aligning.

After adjusting the neutral safety switch, check to ensure the car will only start in NEUTRAL or PARK.

The back-up light switch is usually on the gear shifter assembly.

Align the flats of the new switch with those on the shift shaft, fitting it over the shaft and onto the transmission.

No, the backup light and Neutral start switch are pre-adjusted at the factory and do not require further adjustment.

Check the dark blue wire for an open.

Lower the vehicle and disconnect the electrical and vacuum connectors from the cruise control servo, if equipped, then remove the servo and set it aside.

Make sure the steering column lock allows the key to go into the Lock position only when the shift lever is in Park (automatic transaxle) or Reverse (manual transaxle).
