The neutral safety switch in the shifter is worn out. It detects when the car is in park or neutral.

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.

when I have a no start condition I work the maul - d6b1e99.gif

Fig. Fig. 2: Adjusting the neutral safety 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.

2001 Ford explorer sports trac put rebuild transmission in now it will not start move lever back and forth in park or neutral no good

now it will not start move lever back and forth in park or neutral no good ????? When you turn the key to the start position ,what happens ? Nothing ? I'am assuming this because of your statement about moving the gear selector from park to neutral . The first thing to do would be to look at wiring diagrams to see what all is involved in the starter electrical circuits . Then understanding how the electrical circuits work an then using a DVOM - digital volt ohmmeter to test the electrical circuits .

Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine . Under system click on engine , then under subsystem click on starting . Click the search button then the blue link . Looking at the diagram I see the fuse that sends battery voltage to an through the park neutral switch to the starter relay . You can test for B+ voltage at pin 85 , if when in park you see B+ voltage there ,nothing is wrong with the park neutral switch. Pin 30 should also have battery voltage . Using a piece of 12 Gage wire , jump pin 30 & 87 , that is , where the relay plugs into in the fuse / relay box. If the starter an cables are good ,the starter will crank the engine over .

My 01 montero sport goes into park, but won't crank. i shifting to neutral and starting it but still nothing. how do i adjust the linkage tighter to make the gear fully shift into park?

With the key turned to start and moving the gear selector bad and forth thru neutral and park range proves the safety switch you talking about needs adjusting. Proper diagnosing will save you time and energy. Test your starting circuit. Test the starter solenoid and motor.

1999 Ford ranger 4x4 3.0 LITER mind of it's own when wants to start. All lights come on as the should won't CRANK any suggestions tried fuses still n9 luck?

Rock it back and forth with pressure in either direction on gear selector. Manual or auto can have a safety switch after 1991. If sensor fails to detect park or neutral, no start.

How do I fix the transmission problem? The car is moving forward at neutral, drive and low gear, and switching to parking mode at reverse and parking. The car is not backing up at all.

Transmission may now be toast since you continued to drive it when maybe low on fluid or torque converter had failed. How long since last fluid and filter change? Ever?

I have a 1990 Ford Taurus 3.0 V6 station wagon that has trouble starting.

I am not sure of the auto transmission sensor, but you are absolutely right, there is shift selector that tells the on board computer the car is in neutral or park. any other position and it will not start. I would say it would be located on the transmission where the shift cable hooks to the transmission. I can't remember weather it is on the outside or in the trans itself. It would make sense for it to be on the outside.
I hope I was of some help.

It wont crank over to start

Hi. well we have to start somewhere, turn on the lights, are they bright? checking battery condition.
Next, auto or manual?
auto, make sure shifter is in park. work it back and forth a couple times or try starting in the neutral position.

Manual trans? there should be a clutch safety switch. these are often located on the clutch pedal mounting mounting assembly.
Are the battery cables In good condition? terminals clean and tight?
did you try a jump start?
these are some things that might shed light on the problem.

77 ford f 250 400ci not start no power at dash check silinode relay have power on i and s sides and on the starter side, ignotion has power to but nothing

I would strongly suggest checking all the battery cables and terminals for good clean connections. Then I would suggest trying to move the gear selector from park to neutral or just back and forth while trying to start. If you get a click or it starts it's likely that you have a bad neutral safety switch.
If this doesn't work ensure the vehicle is in park with the wheels chalked and us a remote starter button, or just jump the solenoid to see if the starter functions.

Safety switch in transmission ?

Your Gear Position Sensor is failing. It's common on these models for this part to fail. It's common for the check engine light to also come on and store a code for this sensor.
