  Q: How to service and repair the Neutral Safety Switch for the 4L60-E/4L65-E transmission on Cadillac Escalade?

  A:

  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.

  Q: How to replace the Neutral Safety Switch on the 4L80-E/4L85-E transmission on Cadillac Escalade?

  A:

  To replace the park/neutral position switch on the 4 l 80- e/4l 85- e transmission, start by using the park motor to take the selection to the neutral and then park and apply the park. If the car is four-wheel drive (4WD), the front propeller shaft should be removed. Lift and adequately support the vehicle, then remove park/neutral position (PNP) switch electrical connectors. Then remove range selector end from the range selector lever ball stud, control lever to the manual shaft nut, and remove the range selector control lever from the manual shaft nt. Next, remove the pnp switch bolts and pull the pnp switch off the manual shaft; if it does not slide out easily, file the outer edge of the manual shaft to remove burrs. Removal is also easy: it is enough to remove a switch from a shaft and at the same time remove the mounting bracket from transmission bosses. In the case where a new pnp switch will be wired, it will have a positive assurance bracket attached to it, thus rendering the need of a park neutral switch aligner redundant. Mount the pnp switch bolts with with finger tight tension, then hold the connecting tool, j 41364-a park neutral switch aligner (J 41364-A) on the pnp switch ensuring that the two slots on the switch fall in the lower tabs of the tool. Turn the j 41364-a in both ways to place the upper locator pin into the slot on the top of the switch then tighten the bolts to 25 nm (18 ft. Lbs.). Take off the j 41364-a from the pnp switch and, if necessary, remove the positive assurance bracket. Replace the control lever on the manual shaft with the nut (torque to 25 Nm or 18 ft. Lbs.), mount the end of the range selector cable to the ball stud of the range selector lever, and connect the pnp switch electrical connections. Instead if four wd, reinstall front pro retier shaft, lower the veh, verify the pnp switch so that it will work properly, engine will start only in the park (P) or neu tral (N). If it doesn't, then replace switch.
