  Q: How to replace the Neutral Safety Switch on Chevrolet Astro?

  A: When replacing the park/neutral position switch always start by applying the parking brake shift the transmission into the neutral position. Support the vehicle while raising it and remove the nut holding the transmission control lever to manual shaft and detach the lever. Start by disconnecting the switch electrical connectors then remove all bolts holding the park/neutral position switch to the transmission before taking out the switch from the manual shaft. You should file the manual shaft's outer edge to eliminate any burrs that block easy switch removal. Place the switch hub flats against the manual shaft flats then slide the switch until the mounting bracket touches the transmission's mounting bosses. Hold off from securing the bolts at this time. Because of this operation secure the switch to the transmission with two bolts while keeping them loose. Position the j 41364-a neutral position adjustment tool (J 41364-A) onto the switch where the slots must match the tool's tabs. Synchronize the upper locator point of the tool with the switch slot by tool rotation then torque bolt tightening to 25 nm (18 ft. Lbs.). Put the tool aside then attach electrical wires to the switch before securing the transmission control lever with its nut to 25 nm (18 ft. Lbs.). Check the switch operation from a lowered position to make sure the engine starts only when the selector is placed in p (Park) or n (Neutral). Perform a new switch installation when the existing switch exhibits operational failures.
