How to replace neutral sefty switch?

well could be two things. either your transmission has crapped out on you. or you have a shifter linkage issue. which means when the car is in park its not really in park. try this. move the shifter and see if the car moves in a different gear then what it says it is in . so if it moves in neutral it could be drive and reverse is neutral. if it does not reverse at all. time for a new trany is my guess.

The shifter is connected to a cable that is then attached to a small lever on the transmission. Disconnet the cable at the transmission end and you'll likely be able to physically put it in neutral. Disconnect it at the shifter end and you'll be able to move the shifter to trigger the neutral lockout switch and allow the car to start. You can also short this switch to trick the car into thinking it is in neutral.

This could be the problem. If your dash indicator is showing reverse but the transmission is in park it could be the safety switch. I'm not talking about the safety switch in the transmission though. In automatics they put a second switch to kill the starter from engaging. You need to adjust the linkage. If your shifter isn't actually on the column but the indicators are there is a cable that attaches the floor shift to the column and that is adjustable. Put the Floor shifter in Park and turn the column section nearest the dash by hand until you find park. Then adjust the cable length as needed. If all you have is the column shift it is still a cable adjustment. Set the emergency brake, drop the shifter to low 1 and adjust the cable linkage by loosening it on the transmission and manually move it all the way to low 1 then tighten it down then move the shifter to park and repeat teh adjustment process to verify that it is properly aligned. Lock the linkage back down and see if the vehicle will start, if it doesn't move the shifter to neutral and try to start the vehicle if the vehicle starts then check the column shift safety switch at the park position to make sure it is still in place and working. Typically, if the vehicle won't start in Park or Neutral it is more likely to be the Transmission neutral safety switch.

There is usually a switch mounted on the transmission. Perhaps it has gotten loose or something is worn or broken. Your gear selection goes park, reverse, neutral and drive. Since the switch is not coming on from park to reverse but it kinda does if you go past reverse (neutral) then it sounds like the switch has moved from its original place. That's why I think it is loose. Good Luck!

good posibility is brake light switch. this sits up behind your brake pedal. if you can move gear shifter with key just in between off and acc put shifter in position just between drive and neutral or park and reverse see if you can get it into gear from there if so that is most likely issue

Is there any warning lights or malfunction besides this?? There are three main parts that may cause this: Park/Neutral safety switch(located on the transmission), Brake pedal switch(located at the brake pedal), Shift lock solenoid(located below the shifter). P/N safety switch prevents the shifter from shifting out of (P) or shifting into (R/P) while vehicle is in motion. Brake pedal switch sends a signal to release the shifter lock to shift out of park. Shift lock, locks the shifter as describe above and is located at the shifter base. I recommend inspection/replacement of the shift lock solenoid and P/N safety switch as its an intermitted problem. Hopefully this helps

1.Shifter linkage could be out of adjustment, and not allowing the Neutral safety switch to be bypassed, when in the Park position.

The shift linkage, could move the arm of the neutral safety switch far enough, to bypass it when the shifter is in Neutral, but not far enough when the shifter is in Park.

2.Perhaps the Neutral safety switch is bad, or has come loose on it's mount, and is out of position.

it sounds like your gearshift cable is broken..if you can jack up vehicle and support it safely,get someone to move shifter and look on driver's side of transmission and see if linkage is moving on trans..linkage is up near top of trans..i have seen this problem before

ya the neutral safety switch would cause that if the car doesnt think its in park or neutral it wont start

I had the same problem. My backup lights wouldn't come on in when I put the auto. trans. shifter into the Reverse position. They WOULD come on briefly as I moved the shifter from Park position into Reverse, but would go off again when the shifter reached the Reverse detent. I got the solution from the Haynes service manual, in which the relevant switch is referred to as something like the neutral safety switch. Check on top of the steering column close to the firewall. Set the parking brake, then move the auto. trans. shifter into Neutral position. Get under the dash and rotate the neutral safety switch clockwise as far as it will go. Then move the shifter into the Park position, and your switch should be set. If the backup lights don't come on now when the shifter is put into Reverse position with the ignition switch 'on', there may be another problem.
