2005 Chevrolet Express 2500 Neutral Safety Switch Parts Questions & Experts Answers

• Q: How to replace the Neutral Safety Switch on a 4L80-E/4L85-E transmission on 2005 Chevrolet Express 2500?

  A: The replacement process for the park/neutral position switch requires users to engage the park brake followed by placing the transmission in neutral position. Use a jack to lift the vehicle and remove the nut between the transmission control lever and manual shaft before extracting the control lever. First disconnect all electrical connectors from the switch then remove the bolts which secure the park/neutral position switch to the transmission before sliding out the switch from the manual shaft. The operation of the switch should be smooth but if it remains stuck file down the manual shaft's outer edge to remove any burrs. Start by matching the switch hub flats with manual shaft flats before sliding the assembly onto the shaft until it makes contact with transmission bosses. When installing a new switch system the provided positive assurance bracket removes the requirement for a neutral position adjustment tool. Secure the switch with two bolts at the minimum tension and then position the j 41364-a neutral position adjustment tool (J 41364-A) onto the switch body so its slots match the tool tabs. Tighten the bolts to 25 nm (18 ft. Lbs.) after the upper locator pin on the tool aligns with the switch slot. You must detach the j 41364-a component and also remove the positive assurance bracket when needed. Connect the electrical connectors to the switch before installing the transmission control lever by tightening the nut to 25 nm (18 ft. Lbs.). Finally, lower the vehicle and check the switch for proper operation, ensuring the engine starts only in the p (Park) or n (Neutral) positions; check for switch replacement when the device fails to function correctly.
