How to service and repair the 4L80-E Automatic Transmission's Neutral Safety Switch on GMC C3500?

First, use the parking brake and position the transmission in neutral to begin working on the transmission position switch/sensor of a 4l80-e automatic transmission. Elevate the vehicle and remove the bolt that holds the transmission control lever to the manual shaft and after that take out the lever. Don't connect the wiring harness to the vehicle harness near the park neutral position switch connector to avoid breaking it. After that, remove the two bolts connecting the park/neutral position switch to the transmission, then get off the switch from the manual shaft. If the switch doesn't pull off, then carefully file down the rough edge of the manual shaft to help it slide off. Place the switch on the manual shaft of the transmission, line up the hubs of both parts and push the switch until it rests against the bosses in place. Fit the switch to the box by securing it with two bolts that you do not tighten yet. Place the j41364-a tool onto the neutral/park switch and make certain the tool's lower tabs lock into the two holes on the switch. Place the upper locator pin above the matching slot on the switch and then tighten the screws to 25 nm (18 ft. Lbs.). Take out the tool and slide the wiring harness connector into the other harness at the vehicle. Connect the transmission control lever to the manual shaft then tighten the nut using a torque of 25 nm (18 ft. Lbs.). Drop down the vehicle and make sure the switch functions as needed, allowing the engine to start when set to p (Park) or n (Neutral).
