Where is the neutral safety switch


The backup lamps will light whenever the ignition switch is in the RUNposition and the transaxle is in REVERSE. On older vehicles, this function was handled by a dedicated switch with a name such as the Neutral/Safety Backup Light Switch, or something similar. This switch was designed to keep the engine from starting in any gear except PARK and/or NEUTRAL. The switch contacts also activated the backup lights when the transaxle was placed in REVERSE.

On the vehicles covered by this manual, the backup lamp control function is part of an integrated switch called the Transaxle Range switch (sometimes also called the Park/Neutral Position or PNP switch). In addition to turning on the backup lights, the Transaxle Range switches primary function is to transmit to the Powertrain Control Module (PCM) the driver's transaxle range selection. The PCM uses this information to control both engine and transaxle functions electronically.

The Transaxle Range switch is mounted externally on the transaxle. New service replacement switches come pinned in the NEUTRAL position and no adjustment should be necessary. Please note that if the switch requires adjustment, GM recommends that their special tool J 41545 Park/Neutral Switch Alignment Tool be used to properly adjust the Transaxle Range switch, if required.



Removal & Installation

  1. Apply the parking brake and block the front wheels.
  2. Place the transaxle gear selector to NEUTRAL.
  3. Remove the air intake duct to access the switch located on the top of the transaxle at the range selector cable and arm.
  4. Disconnect the transaxle range selector cable.
  5. Detach the electrical connectors from the range selector switch.
  6. Remove the range selector lever retaining nut and lift off the lever.
  7. Unfasten the range selector switch mounting bolts, then remove the switch from the transaxle manual shaft.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Test/Service/Replace Neutral Safety Switch
Most neutral safety switches are combinations of a neutral safety switch and a backup lamp switch. Others have separate units for these two distinct functions. When the reverse light switch is not part of the neutral safety switch, it seldom needs adjustment, as it is directly activated by the transmission or the gear selector linkage.
f_ttat_t3.20.jpg Typical location of a neutral safety switch on a transaxle. Reprinted with permission of Ford Motor Company. A neutral safety switch allows current to pass from the starter switch to the starter when the lever is placed in the P or N position. Some neutral safety switches are nonadjustable. If these prevent starting in the P or N position and the gear selector linkage is correctly adjusted, they should be replaced.
To adjust a typical neutral safety switch:
  • Place the shift lever in neutral.
  • Loosen the attaching bolts for the switch.
  • Using the angling pin, move the switch until the pin falls into the hole in its rotor.
  • Tighten the attaching bolts.
  • Recheck the switch for continuity. If no voltage is present, replace the switch.
  • The switch sometimes controls the operation of the back-up lights also. With the engine off and the key on, put the selector in reverse position. Check the back-up lights to see that they are on. Then, check in the drive position to see that they are out.

I have a 1992 buick roadmaster limited edition and my reverse lights stay on all the time how do i fix this problem


Hi...sounds like your Neutral Safety Switch needs to be adjusted. Loosen screws enough to slide switch one way or the other until your backup lights go out when the vehicle is in park, then re-tighten screws. Check to make sure backup lights come on only in Reverse. Here is a link showing the location of your Neutral Safety Switch: http://www.autozone.com/autozone/parts/1992-Buick-Roadmaster/Neutral-Safety-Switch/_/N-iwj89Z9cid6 (copy and paste entire link into your browser if the link is not live)

My back up lights don't work, what should i do?


check 15 amp fuse (may be in engine compartment relay box). If fuse is good, check switch on transmission. To check the switch, pull the connector off and short the two outer terminals together. With the key on, the backup light should come on. If they do, replace the switch. The switch looks something like this:

29b5196.gif409c52d.gif
The neutral safety switch, otherwise known as the park/neutral position switch, prevents the vehicle from being started in any position other than PARK and NEUTRAL. It also functions as the back-up lamp switch.
The neutral safely switch is threaded into the transmission case. When the gearshift lever is placed in either the PARK or NEUTRAL position, a cam, which is attached to the transmission throttle lever inside the transmission, contacts the neutral safety switch and provides a ground to complete the starter solenoid circuit. The back-up light switch is incorporated into the neutral safety switch.
The center terminal is for the neutral safety switch and the two outer terminals are for the back-up lights.
There is no adjustment for the switch. If a malfunction occurs, the switch must be removed and replaced.

When I have a no start condition I work the maul selector from park to low 1 back and forth and the car starts


Your safety interlock switch is going out or is not adjusted properly. There is a procedure for adjusting the switch. The switch is on the transmission in the engine compartment. If you want to adjust the switch, loosen the botls holding the switch and follow steps 7-8 below. Else, you can just replace the switch entirely by following all steps.

The neutral start and backup switch are one unit mounted on the top left end of the transaxle. The neutral start portion of the switch allows electrical current to travel to the ignition system when the shift selector is in park or neutral only. The vehicle will not start when the selector is in any other gear. The backup portion operates the rear backup lamps when selector is in the reverse gear.


REMOVAL & INSTALLATION See Figures 1 and 2

  1. Make sure the shift selector in the Park position, then apply the emergency brake.
  2. Disconnect the negative battery cable.
  3. Disengage the neutral start switch electrical connector, then remove the shift control lever on top of the switch.
  4. Remove the two neutral switch attaching bolts, then remove the switch.

To install:

  1. Install the switch on the manual shaft.
  2. Loosely install the two attaching bolts and washers.
  3. Insert a No. 43 drill (0.089 in.) through the hole.
  4. Tighten the attaching bolts to 7-9 ft. lbs. (9-12 Nm), then remove the drill.
  5. Engage the switch electrical connector, then connect the negative battery cable.

There is a shortage somewhere in the panel where I change my gears, my reverse lights will come on and then go off but if I jiggle the gear shift they will light back up. How can I repair this problem?


It sounds like a bad connection or the switch needs adjustment,to the backup lites.I think the switch is under the panel or where the center console is and the Emergency brake lever.,but first check on the transmission it may be located there! The neutral saftey sw. and back up lites sw. may be in the same switch housing! There is a cable that selects the transmission into gear.

1971 ford f100 pickup neutral safety switch wiring color code


Ford Neutral Safety Switch; Ford Reverse Light Switch; Backup Light Switch.

The Neutral Safety Switch wires in my 1971 Ford F100 are orange with a blue stripe.
The Reverse, or Backup Light Switch wires are black with a red stripe.

There are two sets of two wires across this combined neutral safety and backup light switch, for a total of 4 wires. Photos are at the end of this post.

The switch for the 1971 Ford F100 pickup truck is the same as in many other years and models. For details, including parts numbers, see the following quote from an expert at Ford Truck Enthusiasts:
http://www.ford-trucks.com/forums/287185-back-up-light-and-neutral-safety-switch-2.html#post5601846

The neutral switch also controls the backup lights, and is the same 1967/77.

C7TZ-7A247-A .. Neutral/Backup Switch (Motorcraft SW-600)

There is no separate backup light switch..except on 1967/68 F350's.

Neutral switch location 1967/77:

The plastic half moon shaped neutral safety switch mounts on the outside lower portion of the steering column (NOT on the transmission!).

It's activated by an inverted Y shaped lever that snaps on the shift tube

D0TZ-7B097-B .. Lever, Neutral Switch Actuator = From FTE sponsor DIRECT FORD PARTS: Ford suggested retail price: $18.72 / FTE member net: $13.23.

The switch is also still available from Ford, but the website is down so I can't post the list & net prices. .

1978 is the FIRST year the F100/350's have the neutral switch mounted on the transmission. __________________

The neutral switch is installed on the steering column near the firewall, with 5/8" bolts into the steering column (visible hole) and down column from a rectangular opening in the column housing. The actuating lever for the switch is attached to the gear shift shaft inside the housing; the lever is visibly protruding from the opening in this image.

I need a fuse diagram for a jeep Grand cherokke larado


A very common issue with that particular transmission is the "Neutral Safety Switch". Check fuses of course. But if that is ok then try this. The neutral safety switch is located on the drivers side of the transmission case just above the trans pan. Pull off the three wire connector and jump to two out board terminels (a paper clip will do). Turn on the key and your backup lites should be on. FYI: By the way the center terminel is the neutral safety part (it grounds to the trans). Replacing it is a matter of unscrewing it . Be aware you will get some trans fluid leakage and this switch has a gasket that may or may not stick to the case. Make sure the gasket is there or you will have a leak. (new one would be good but they can be reused) There have also been issues with the rear lighting harness connector located in the rear corners by the tail lites. (usually those create lamp outage warnings with the Vehicle Information Center) Good luck
