neutral safety switch - gear range sensor replacement instructions?

It's bolted to the side of the transmission, around the shift selector shaft. A couple bolts and unplug the harness and your there. It will have to be adjusted to the correct position. The instructions to change out the neutral safety switch are in the diagrams below.

not going into gear it tell me after it worms up that the shift range habitant I'm not to sure what that means thanks

You will find that sensor on the side of the transmission housing (drivers side). It has a lever on it that attaches it to the linkage coming from the shift lever on the steering column. There will be a connector and some wires attached to it as well. this guide can help test it.

Check out the diagrams (Below). Please let us know what happens.

Okay, so I am getting no crank when I turn over key. Looked at neutral safety switch and it is bad long story short was in a field a couple months back in y’all grass. The grass caught on fire and roasted the switch and the 2 plugs. I cut all the wires to see if I could jump 2 of the wires to get start. I found a co start 12v power. I believe it was a black wire. But can’t find wire that has 12v in crank mode so therefore can’t get it to start when ignition is turned over. Now there was a wire down there I could touch the constant black wire to and get the starter to turn over but it would do it continuously and in 2 acc mode. Need answers on how to bypass the switch.

Hey DALTON SCHMIDT,

I can provide you with a wiring diagram but really you should replace the switch and repair the wiring. I cannot advise you to bypass this system. You should have a yellow and a purple/white wire that control the switch.

There are also 2 fuses in this circuit that you may have to replace.

ignition c in the under hood fuse box.
crank fuse in the interior fuse panel (left side of dash).

It is a safety system and should be repaired and working properly.

You could source a replacement switch very cheaply.
You should also be able to find a wiring pigtail to replace the melted plug connection.

The instructions on how to replace the switch are attached also.

Unfortunately they don't provide an application chart to show which switch is open and which is closed for each gear. This means you would need to try different combinations in order to find out what the correct combination is. Keep in mind the PCM supplies 12 volts to each of these circuits and then it goes open for the switches that are not on in each gear. So you will need to have a combination for park/neutral and then one for drive then reverse so that the vehicle will operate.

It will be far easier to just replace the switch if this is your issue. I included the info about this. Let me know if you have questions. Thanks

There aren't any codes coming up. Thursday when I got back to my truck everything was working fine but today it started doing the same thing I discribed earlier plus it was having shifting problems. Is your response still the same with this additional information? Thank you

Yes definitely, that info helps. Yes my response would be the same and like I said GM has an updated part for this issue. Neutral Back Up Switch. Also next time post to your earlier post, thanks.

How do i replace the shift neutral switch?

welcome to the forum, my info shows this.

How do I replace my shift neutral switch? Thanks.

PARK/NEUTRAL POSITION SWITCH REPLACEMENT/ADJUSTMENT *Tool Required: J 41364-A Neutral Position Adjustment Tool *Apply the parking brake. *Shift the transmission into neutral.

REMOVE OR DISCONNECT IMPORTANT: The transmission must be positioned into the mechanical neutral position prior to performing this adjustment procedure. The transmission control lever can be positioned to mechanical neutral position by rotating the control lever clockwise until it reaches it's full stop position, and then moving the shift control lever counter-clockwise two detents. 1.Negative battery cable. 2.Shift cable end from the transmission shift control lever by pulling the cable end from the transmission shift control lever stud ball. 3.Nut securing the transmission shift control lever to the manual shaft. 4.Wiring harness connector from the switch. 5.Two bolts securing the switch to the transmission. 6.Switch from the manual shaft. *If the switch does not slide off of the manual shaft, lightly file the outer edge of the manual shaft to remove any burrs from the shaft. INSTALL OR CONNECT

ADJUST 1.Position Tool J 41364-A onto the park/neutral position switch. Ensure that the two slots on the switch(where manual shaft is inserted) are lined up with the lower two tabs on the tool. Rotate the tool until the upper locator pin on the tool is lined up with the slot on the top of the switch 2.Switch to the transmission manual shaft. *Before sliding the switch onto shaft, it may be necessary to lightly file the outer edge of the shaft to remove any burrs from the shaft. *Align the switch hub flats with the manual shaft flats. *Slide the switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission. 3.Switch to transmission with two bolts. TIGHTEN *Bolts securing the switch to 28 Nm (21 lb. ft.). 4.Remove Tool J 41364 from the switch. 5.Wiring harness connectors to the switch. 6.Transmission control lever to the manual shaft. 7.Transmission control lever to the manual shaft with the nut. TIGHTEN *Control lever nut to 28 Nm (21 lb. ft.). 8.Lower vehicle 9.Negative battery cable. INSPECT 1.Check the switch for proper operation. *The engine must start in the "P" (Park) or "N" (Neutral) positions only. If adjustments is required, loosening the switch retaining bolts and rotate the switch slightly, then tighten the bolts and check the switch for proper operation.

Where is the neutral safety switch located?

The neutral safety switch is located on the steering column. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
