  Q: What tools are required to service and repair the Neutral Safety Switch on Chevrolet Express 3500?

  A: The tools and equipment needed to service and repair the transmission position switch/sensor include: neutral position adjustment tool (J 41364-A). Start by placing the parking brake and shifting the transmission in neutral. Pulled negative Battery Cable, removed nut from the end of the tranmission control lever to the manual shaft and removed lever. Next, you will disconnect the wiring harness connector from the park/ neutral position switch and remove the two bolts which hold the switch to the transmission after which you will be able to take off the switch on the manual shaft. For installation, place the neutral position adjustment tool (J 41364-A) on the park/neutral position switch where the two slots on the switch fall into the lower tabs of the tool. Twist the tool until the upper locator pin meets the slot on the top of the switch. When the switch does not come off the manual shaft, file the outer edge of the shaft removing any burrs. Mount the switch on the transmission manual shaft by placing into place according to the switch hub flats and the manual shaft flats, until the mounting bracket is in contact with the transmission mounting bosses. Install the switch to the transmission with the two bolts and tighten them to 28 nm (21 ft. Lbs.). Further, take off the neutral position adjustment tool (J 41364-A), connect the wiring harness connector back to the switch, and reinstall the transmission control lever to the manual shaft with the nut that should be tightened to 28 nm (21 ft. Lbs.). Finally, lower down again, connect the negative Battery Cable and ensure the switch works as it should, and only the engine can start in the p (Park), n (Neutral).
