Neutral safety location and adjustment - Cars & Trucks

The neutral safety switch is located on the transmission shift lever. Its held onto the transmission case by 2 bolts in slotted holes. You will need to remove the kickdown lever. The switch will slip off the shift lever with just a little pry if dirty. Replace the switch while the transmission is in neutral. There is a small hole in the side of the switch to stick a small pin or awl into to locate the neutral position of the switch. I would try to adjust the old switch before replacing it.

On top of the transmission, has a triangle shape. Backup light switch is incorporated into it. Has to be adjusted to Neutral position with transmission in Neutral to get it right. Be careful to chock the tires so the car cannot roll and use the hand brake for added safety.

the neutral safety switch. is a switch located in the shifter mechanism that keeps the engine from starting if the transmission isn't in park or neutral.There are no adjustments for this switch. It is a simple steel ball type switch in a rectangular housing that is held with two screws to the shifter mechanism.

Neutral safety switch is located at the bottom of the steering column, on top of the column. If you suspect it to be bad, you can use a jumper wire to eliminate it and see if truck will start normally. Note that if it is bad, and you replace it, it must be adjusted to work properly. The new switch should come with adjustment instructions.

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.
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.

There may not be a fuse in that circuit. Much more common issues involve the neutral safety switch. Try starting in neutral and then on either side of neutral. These safety switches sometimes go out of adjustment, or fail.

The neutral safety switch is located on the side of the transmission and it is usually attached behind the shifter linkage and it is secured with two small bolts that can be loosened up to allow for adjustment of the neutral safety switch.

To adjust the neutral safety switch place the transmission into neutral, (block the tires) there is a notch or and indent marker on the housing of the neutral safety switch that should be lined up with a line on the face of the collar that is around the shifter detent shaft, and if they are not in alignment then loosen the two bolts that secure the neutral safety switch and then turn the neutral safety switch until they are aligned and then tighten the securing bolts to the neutral safety switch, and then test the starter. If the starter fails to engage then either the neutral safety switch is faulty, the neutral safety switch has been by-passed all this time and the by-pass (I will usually find things like a paper clip shoved into the vehicles wire connector with electrical tape around it) has fallen out of the wire connector from the vehicle wiring harness, or the battery just went dead. if you have the neutral safety switch from the old transmission still available try using it to test the neutral safety circuit. I have provided you with an image to help assist you adjust the neutral safety switch.

yes its the neutral safety switch its on side of you transmission easy to change

Neutral Safety/Back-up Light Switch

This is a combination switch which controls both Neutral Safety and Back-up lamp circuits.

C6 Transmission



C6 neutral start switch

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle on jackstands.
3. Remove the downshift linkage rod return spring at the low-reverse servo cover.
4. Coat the outer lever attaching nut with penetrating oil. Remove the nut and lever.
5. Remove the 2 switch attaching bolts, disconnect the wiring at the connectors and remove the switch.
6. Installation is the reverse of removal. Adjust the switch and tighten the bolts to 55-75 inch lbs. (6.2-8.5 Nm).
7. Remove the jackstands and lower the vehicle.
8. Connect the negative battery cable.

AOD Transmission



Removing the AOD neutral start switch

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle on jackstands.
3. Disconnect the wiring from the switch.
4. Using a deep socket, unscrew the switch.
5. Installation is the reverse of removal. Tighten the switch to 10 ft. lbs. (14 Nm).
6. Remove the jackstands and lower the vehicle.
7. Connect the negative battery cable.

4R70W Transmission




Removing the Manual Lever Position (MLP) sensor

As of 1994, the neutral safety switch is referred to as a Manual Lever Position Sensor (MLP).

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle on jackstands.
3. Disengage the harness connector from the MLP sensor.
4. Remove the 2 sensor attaching bolts and remove the sensor.

To install:

1. Install the MLP sensor and install retaining bolts. Do not tighten, the sensor requires adjustment.
2. Adjust the MLP sensor then tighten attaching screws to 80-100 inch lbs. (9-11 Nm).
3. Remove the jackstands and lower the vehicle.
4. Connect the negative battery cable.

ADJUSTMENT

C6 Transmission

1. Hold the steering column transmission selector lever against the Neutral stop.
2. Move the sliding block assembly on the neutral switch to the Neutral position and insert a 0.091 in. (2.3mm) gauge pin in the alignment hole on the terminal side of the switch.
3. Move the switch assembly housing so that the sliding block contacts the actuating pin lever. Secure the switch to the outer tube of the steering column and remove the gauge pin.
4. Check the operation of the switch. The engine should only start in Neutral and Park .

4R70W Transmission




Adjusting the MLP sensor

Park is the last detent when the manual control lever is full forward. Return 2 detents toward the output shaft for Neutral.

1. Position the manual control lever in Neutral .
2. Insert Gear Position Sensor Adjuster tool T93P-700 10-A or equivalent, into the slots.
3. Align all 3 slots on the MLP sensor with 3 tabs on the tool.
4. Tighten the attaching screws to 80-100 inch lbs. (9-11 Nm).

I hope help you. Good luck (rated this help).
