    No telling! Very hard to diagnose from here. Best solution, take it in and have it diagnosed by professional technician. You may have forgotten to reconnect something, OR you damaged/ disturbed something.... do you have a CHECK ENGINE light? If so, find out what the trouble code is.

Sorry!... Not a congruent description of problem. Apparently you damages something (wire harness perhaps) which was already weak/deteriorated. Solution, do a visual inspection of the engine wiring harness in the area of the tranmission. Hopefully you'll get lucky.

How do you replace a neutral safety switch on a saturn sl1 2001


It 's a Transmission Range Switch , it tells the pcm more then just park or neutral positions !

Transmission Range Switch Replacement
Ensure the ignition is OFF.
Remove the air cleaner and duct assembly. Refer to Air Cleaner Housing and Duct Assembly Replacement in HVAC.

Disconnect the transaxle range switch harness connectors.
Place the control lever in the full clockwise position.
Notice: If manual shift shaft is rotated excessively, internal damage to the transaxle range switch may occur.
Prevent the manual shift shaft from rotating by holding the control lever while removing the retaining nut from the manual shift shaft. Remove the control lever.
Remove the 2 switch-to-transaxle case bolts and remove the switch.

Install the cable to the control lever and adjust the cable. Refer to Shift Control Cable Adjustment .
Before tightening the transaxle range switch-to-case bolts, proceed to the Adjustment procedure.
Adjustment Procedure
Important: While adjusting the transaxle range switch, always rotate the switch towards the engine to achieve continuity. A diagnostic trouble code DTC P0706 could result if this procedure is not followed.
Important: Digital volt/ohm meter (DVOM) with audible continuity test is preferred. Do not stick the probe in the transaxle range switch terminal hole; use male terminals on the transaxle range switch or faulty readings could occur.
Place the transaxle in Drive (D). Use an ohmmeter or continuity tester to check for continuity across terminals on the selector switch. Rotate the transaxle range switch from the left fender towards the engine until continuity is achieved.
Notice: Refer to Fastener Notice in the Preface section.
Tighten the switch-to-case bolts. After switch-to-case bolts have been tightened, check continuity.

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.

P0707 transaxle range swutch- open circut


You can start by unplugging the sensor and look for bend pins or rust in the connector. Once this is done you can try re-adjusting the range switch.

This is from www.hmaservice.com.
1. Place the selector lever in the "N" (Neutral) position.
2. Loosen the manual control lever lock nut to separate the cable and lever.
3. Place the manual control lever in the "N" (Neutral) position.
4. Turn the transaxle range switch body until the 12 mm (.47 in.) wide end of the manual control lever aligns with the switch body flange [12 mm (0.472 in.) wide portion].
5. Tighten the attaching bolts (2 pcs.) to the specified torque.
When setting up the switch body, be careful O-ring does not drop from the switch body. Tighten the attaching bolts carefully.
6. Make sure that the selector lever is in the "N" (Neutral) position.
7. Adjust the flange nut so that there is no slack in the control cable and make sure that the selector lever operates smoothly.
8. Run the vehicle and confirm that the transaxle is set in each range when the selector lever is shifted to each position.

I have a '99 malibu and the back-up/reverse lights stay on all the time, any thoughts?


Hi, it seems to me the only likely reason is a failed park/neutral switch. What I would do is pull the connector off and use an ohmmeter to check the continuity across the terminals where the pink and light green wires attach. If there is continuity in all gears, replace the switch.

Fig. The shift linkage on the transaxle is fastened with one nut

NOTE The Transaxle Range (TR) switch (also called the park/neutral position switch) also functions as the back-up switch.

  1. Disconnect the negative battery cable.
  2. Remove the shift linkage.
  3. Detach the electrical connector from the switch.
  4. Unfasten the switch-to-transaxle screws/bolts, then remove the switch.

To install:
  1. If installing the old switch, proceed as follows:
    1. Place the shift shaft/control lever in N .
    2. Align the flats of the shift shaft with the switch, then loosely install the mounting bolts.
    3. Insert a gauge pin in the service adjustment hole and rotate the switch until the pin drops to a depth of 9 / 64 in. (9mm).
    4. Tighten the bolts to 18 ft. lbs. (24 Nm), then remove the gauge pin.

  2. If installing a new switch, proceed as follows:
    1. Place the shift shaft/control lever in N .
    2. Align the flats of the shift shaft to the flats in the switch, then install the switch assembly. Tighten the bolts to 18 ft. lbs. (24 Nm).
    3. If the bolt holes do not align with the mounting boss on the transaxle, verify the transaxle is in the N position, do not rotate the switch.
    4. If the shift has been rotated and the pin broken, the switch can be adjusted by following the procedure in Step 5.

  3. Attach the electrical connector to the switch.
  4. Install the shift linkage.
  5. Connect the negative battery cable, then start the engine and check the switch operation.


CAUTION After switch engagement, make sure the engine will only start in P or N.

1996 ford contour transmission range sensor


Transmission range sensor and neutral safety switch are the same thing (when you go to buy the part). It's at the top of your transmission. You'll see the shifting cable connected to it. Here are the instructions for adjustment:
Shift Control Linkage
The transmission shift linkage adjustments must be performed in the order in which they appear.

Column Shift

Place transaxle range selector lever in (D) (OVERDRIVE) position or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS). A weight of 1.4 kg (3 lb) should be hung on the transaxle range selector lever to ensure the lever is located firmly on the (D) (OVERDRIVE) or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS) detent.

Loosen manual control lever-to-control cable retaining nut.

Move transaxle manual control lever to OVERDRIVE position or D (DRIVE) position on vehicles equipped with a transmission control switch (TCS), second detent from most rearward position.

Tighten retaining nut to 17-23 Nm (13-17 lb-ft). Check operation of transaxle in each transmission range position. Make sure that park mechanism and transmission range (TR) sensor are functioning properly.

Floor Shift

Position transaxle range selector lever in DRIVE position against rearward stop. The floor transaxle range selector lever must be held in the rearward position using a constant force of 1.4 kg (3 lb) while linkage is being adjusted.

Loosen manual control lever-to-control cable retaining nut.

Move transaxle manual control lever to DRIVE position, second detent from most rearward position.

Tighten retaining nut to 17-23 Nm (13-17 lb-ft).

Check operation of transaxle in each transmission range position. Make sure that park mechanism and transmission range (TR) sensor are functioning properly.



To take it off, it's a couple of retaining bolts and a wiring harness.
