Question about 2000 GMC Savana

1 Answer

Trasmission will not engage

Trasmission seems to be locked on neutral, ( I'm not sure if it makes sense) I place the shift on P start the engine and could move to D, R, and all the others and nothing will happens, it's like stuck on N. I was told it could be a speed sensor or vacumm sensor.

Engine won't crank over


Might be two different problems.
The no crank issue could be several things including the neutral safety switch, and the other issue could be the brake switch or the shift lock solenoid.
You may be able to shift out of park when the key is between lock and on. And it may crank in neutral.

Hello Richard,

Will it shift back in to reverse, or park? From what you are saying it sounds like a linkage problem, not a serious gearbox problem.

Also, just have a look underneath and make sure it's not dropped a load of ATM fluid overnight.

How to fix the shift cable





  1. Position the steering column transmission shift lever to PARK (P).
  2. Apply the parking brake.
  3. Raise the vehicle. Refer to Vehicle Lifting.




  1. Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the full mechanical stop position.




  1. Slide the black retaining clip forward on the range select lever cable end. This will allow the white lock button to be pushed out.




  1. Push the white lock button on the range select lever cable end out. This will free the metal core adjust body which is inside the cable end. Do not push the white lock button completely out.
  2. Inspect the metal core adjust body on the cable end for dirt or debris that may restrict the travel. Remove any debris by washing the cable end, the metal core adjust body, and the white lock button with soap and water. If the travel of the metal core adjust body remains restricted after the cleaning, replace the cable assembly.
  3. Lower the vehicle.
  4. Ensure that the parking brake is applied.
  5. Turn ON the ignition switch.




  1. Move the transmission shift lever from PARK (P) to 1 and back to PARK (P) ten times.




  1. Place the steering column transmission shift lever in the Park (P) position.
  2. Turn the ignition switch to the OFF position.
  3. Raise the vehicle. Refer to Vehicle Lifting.




  1. Position the transmission range select lever to PARK (P). Rotate the range select lever clockwise until it reaches the mechanical stop position.




  1. Push in the white lock button in order to secure the core adjuster body inside the range select lever cable end.




  1. Slide the black retainer clip rearward over the cable end until it covers the white lock button. Lock the clip over the cable end.
  2. Lower the vehicle.
  3. Turn ON the ignition switch.
  4. Ensure that all the transmission shift light positions (P. R. N. D, 3, 2, 1) engaged and illuminate. If you cannot perform this task, repeat the cable adjustment procedures.
  5. Ensure that the engine starts in PARK (P) and in NEUTRAL (N) positions only. If the engine does not start in PARK (P) and in NEUTRAL (N), the Park/Neutral Position Switch may need adjustment.
  6. Turn the ignition switch to LOCK.
  7. Ensure that the ignition key can only be removed with the transmission shift lever in the PARK (P) position.
  8. Start the engine and check the vehicle transmission shifting. The range select lever cable is properly adjusted if the steering column shift light positions are the same as the transmission engagements.

Neutral safty switch


Back-Up Light Switch/Neutral Safety SwitchREMOVAL & INSTALLATION
(see Figure 1)

On automatic vehicles, functions of both the reverse lamps and the neutral safety switch are controlled by the shift position switch at the base of the shift selector. This multi-circuit switch also sends signals to the various electronic control units (cruise control, automatic transaxle ECU, etc.), keeping them advised of the selected gear.

5d7324d.jpg

Fig. 1: Reverse lamp and neutral safety switch functions are both controlled by a shift position switch at the base of the shift selector

To replace the shift position switch, firmly set the parking brake and block the wheels. Place the shift selector in N. Remove the console. The switch is located on the side of the shift selector, held by 2 bolts or nuts. Unplug the wiring connectors, then remove the switch.

When installing the switch, make sure the switch slider is positioned to align with the shifter arm or tab. Install the switch, tighten the retaining nuts or bolts and connect the wiring. Reinstall the console.

After installing the switch, check that the engine starts only in P or N; the starter should not engage with the shifter in any other position. Check also that the back-up lights come on when the selector is placed in R.

Hope this helps (remember comment and rated this).

How to replace neutral saftey switch on a 1980 cadillac deville?


Use like reference guide for GM Cadillac 1967-1989 Repair Guide Neutral Safety Switch - REMOVAL & INSTALLATION

All Except 1985-89 Eldorado and Seville
See Figure 1
The neutral safety switch prevents the engine from being started in any transmission position except Neutral or Park. The switch is located on the upper side of the steering column under the instrument panel on column shift cars, and inside the shift console on floor shift models.
  1. Remove the console for access on floor shift models.
  2. Disconnect the electrical connectors.
  3. Remove the neutral switch.

To install:
  1. Place 1967-70 column shift lever models in Drive, and 1971 and later models in neutral. Locate the lever tang against the transmission selector plate on column shift models.
  2. Align the slot in the contact support with the hole in the switch. Insert a 3 / 32 in. (2.38mm) diameter pin in place. The switch is now aligned in Drive position.

1973 and later neutral safety switches have a shear-pin installed to aid in proper switch alignment so that insertion of a pin is unnecessary. Moving the shift lever from Neutral shears the pin.
  1. Place the contact support drive slot over the drive tang. Install the switch mounting screws.
  2. Remove the aligning pin. Connect the electrical wiring, and replace the console.
  3. Set the parking brake and hold your foot on the service brake pedal. Check to see that the engine will start only in Park or Neutral.

Fig. 1: Installation of a common neutral safety switch



ADJUSTMENT
See Figure 2
1974 and later cars do not have a neutral safety switch. Instead, these cars have an interlock between the lock and the transmission selector, which is non-adjustable.
  1. Place the shift lever in Neutral.
  2. Move the switch until you can insert a gauge pin, 3 / 32 in. (2.38mm) diameter, into the hole in the switch and through to the alignment hole.
  3. Loosen the switch securing screws. Remove the console first, if necessary.
  4. Tighten the screws and remove the pin.
  5. Step on the brake pedal and check to see that the engine will only start in Neutral or Park.

Fig. 2: Adjustment of a common neutral safety switch


1985-89 Eldorado and Seville
See Figure 3

All neutral safety/back-up light switches come with a small plastic alignment pin installed. Leave this pin in place.
  1. Place the shifter assembly in the Neutral position.
  2. Remove the shifter lever-to-switch nut and the lever.
  3. Disconnect the electrical connector from the neutral safety/back-up light switch.
  4. Remove the neutral safety/back-up light switch-to-transaxle bolts and the switch from the vehicle.

To install:
  1. Position the shifter shaft in the Neutral position.

If using an old switch or the plastic pin (new switch) is broken, install a3/32in. (2.38mm) diameter pin gauge (drill bit) into the neutral safety/back-up light switch; the switch is then locked into its Neutral position.
  1. Align the flats of the shifter shaft and the neutral safety/back-up light, then, align the switch-to-tang on the transaxle. Torque the switch-to-transaxle bolts to 22 ft. lbs. (30 Nm). Remove the pin gauge.
  2. To complete installation, reverse the removal procedures. Make sure that the engine starts only in the Park and Neutral positions.
