  Q: How to replace the Neutral Safety Switch on GMC Envoy?

  A:

  Before replacing the park/neutral position switch start by setting the parking brake and placing the transmission in neutral mode. Begin by hoisting the vehicle and unscrewing the nut which attaches the transmission control lever to the manual shaft before extracting the lever. Evacuate electrical wiring from the switch after which you should detach the mounting bolts which anchor the park/neutral position switch to the transmission and peel the switch free from the manual shaft. You should file the manual shaft outer edge because the switch does not move freely. Individual the switch hub flats with manual shaft flats and move the switch along the shaft until it connects with the transmission's mounting bosses. When replacing a new switch the built-in positive assurance bracket makes neutral position adjustment using tools unnecessary. Secure the switch to the transmission with two bolts slightly tightened before placing the j 41364-a (J 41364-A) park/neutral switch aligner onto the switch with its slots positioned correctly against tool tabs. Use the tool to turn until the top locator pin matches the switch slot before applying torque to 25 n.m (18 lb ft) with the bolts. First remove both the j 41364-a and any positive assurance bracket if present. After reattaching power wires to the switch, install the transmission control lever onto the manual shaft using a nut while tightening the lever nut to 25 n.m (18 lb ft). Finally, lower the vehicle and check the switch for proper operation, ensuring the engine starts only in the p (Park) or n (Neutral) positions; the switch must receive replacement when it fails to perform properly.
