Question 1

How to replace the Neutral Safety Switch on a 4L80-E/4L85-E automatic transmission on Chevrolet Avalanche 1500?

Accepted Answer

Start the replacement procedure for the park/neutral position (PNP) switch by applying your vehicle's park brake while placing the transmission in neutral state. You must unmount the front propeller shaft if your vehicle comes with 4-wheel drive (4WD). Tilt the vehicle at a safe height. Start by removing both the pnp switch electrical connection and the end of the range selector cable from its position on the ball stud of the range selector lever. Start by extracting both the control lever to manual shaft nut and manual shaft control lever before moving onto the pnp switch bolts removal. Remove the pnp switch bolts by turning off the manual shaft and withdraw the pnp switch. A file should be used to smooth the manual shaft's outside portion when the pnp switch fails to move off easily. When installing the pnp switch position it to match the manual shaft flats before sliding it onto the manual shaft until its mounting bracket contacts transmission mounting bosses. New pnp switches accompany a positive assurance bracket which negates the need to use park neutral switch aligners. After finger-tightening the pnp switch bolts, place the j 41364-a park neutral switch aligner (J 41364-A) onto the pnp switch so its lower tabs match the slots. Use the j 41364-a to rotate the switch until its upper locator pin reaches the slot on top before tightening bolts to 25 nm (18 ft. Lbs.). First remove j 41364-a from pnp switch followed by elimination of positive assurance bracket if equipped. After securing the control lever on the manual shaft with a nut setting torque to 25 nm (18 ft. Lbs.), attach the range selector cable end to the range selector lever ball stud before reconnecting the electrical connector of the pnp switch . Drive the vehicle to verify that the engine starts correctly only when placed in p or n positions via the pnp switch; accomplish this step when using a four wheel drive vehicle. Test the switch to determine if it functions properly then replace it with a new one.

Question 2

How to service and repair the Neutral Safety Switch for the 4L60-E/4L65-E transmission on Chevrolet Avalanche 1500?

Accepted Answer

Service and repair procedures for the Neutral Safety Switch of the 4l60-e/4l65-e transmission start after applying the park brake and switching the transmission into neutral position. Start by removing the front propeller shaft when your vehicle has 4-wheel drive (4WD). Support the vehicle properly and unplug all park/neutral position (PNP) switch electrical connectors from their corresponding ports. Start by removing the manual shaft lever nut and then extract its transmission control lever from the manual shaft. Start by removing pnp switch bolts to extract pnp switch from the manual shaft. Manually file away burrs on the manual shaft outer side if the component fails to slide off without resistance. Install the pnp switch by positioning it on the transmission manual shaft with attention to align both sets of flats between the hub and manual shaft then push it forward until the mounting bracket touches the transmission bosses. The use of j 41364-a park neutral switch aligner becomes unnecessary when installing a new pnp switch because the switch comes with an integrated positive assurance bracket. Finger-tighten the pnp switch bolts before applying the park neutral switch aligner (J 41364-A) onto the switch. The two slots on the switch should match the lower tabs on the tool. Tighten the bolts to 25 nm (18 ft. Lbs.) by rotating the tool until the upper locator pin rests precisely on the slot found on top of the switch. Next, remove the park neutral switch aligner (J 41364-A) followed by any positive assurance bracket that might be in place. Install the transmission control lever onto the manual shaft by using the nut and torque it to 25 nm (18 ft. Lbs.) before reattaching the pnp switch electrical connectors. Check the switch operation while lowering the vehicle by reinstalling the front propeller shaft for 4wd systems ensuring the motor starts only when the vehicle is in park (P) or neutral (N). The system requires replacement of the switch when it fails to work correctly.
