Question about 2004 Lincoln Aviator

1 Answer

04 Aviator won't come out of Park on Incline

I removed the access panel and the shift lock actuator appears to be working correctly every time the brake pedal is depressed. The "manual" override doesn't work either. It appears that the problem is the force on the drivetrain/transmission when the vehicle is on a hill rather than an electrical problem. The brake lights work fine.

    Thanks. Any reason why this would have just started happening that you are aware of? We have had the vehicle since it was new. The vehicle now has $75,000 miles and we are just now having this problem.

    The dealer said there is a TSB on this issue that basically just says to set the Parking Brake as you have suggested. There has been a clicking noise coming from the rear and the Parking Brake does not work. I assume this is the crumbled pads that others have mentioned. The dealer says pads are $140 and about $100 to put them on. Wow!

Try rocking the truck while attempting to shift out of park. In the future always set your parking brake before shifting to park and releasing the foot brake. This will keep the weight of the truck from binding the parking lock in the Trans.

Holden cruze 2009 key stuck in the ignition won't go to off position , can't get it out of park .What is the problem ?


Is it shifter on the floor ?
Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control actuator , and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

GM had problems with these ! Has a TSB - technical service bulletin !
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

My 2003 GMC ENVOY won't shift out of park


Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid


?€¢
The automatic transmission shift lock control switch

With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.

You have a shift interlock problem . What kind of vehicle ? a mercury what ?
Shift Interlock System
The shift interlock system prevents shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted on the selector lever. If the ignition switch is in the RUN position, the shift lock actuator is disabled when the brake pedal is depressed.
If the selector lever will not move out of PARK with the key in the ON position and the brake pedal depressed, it will need to be unlocked manually.
Do the brake lights work ?

My gear shift is stuck in park. The car starts up fine, but shifter wont budge.


the fuse is bad for shift lock solenoid. Read owner manual section on brak-shift interlock. Check fuse for nbrake lights. Brake lights work.

Owner manual has emergency by pass procedure. I think you turn key to OFF and then shift to neutral and start car then. Next time in park, you have to repeat.

Brake light fuse is blown or the shift lock solenoid has gone bad. It is supposed to release the gear shift selector at the same time the brake is pressed.

  • GEAR SELECTOR LEVER - INCREASED EFFORT TO SHIFT FROM DRIVE TO PARK
Publication Date: November 1, 2004
FORD: 2002-2005 Explorer, Mountaineer ISSUE: Some 2002-2005 Explorer 4dr/Mountaineer vehicles, may require a greater effort to move the gear selector lever (shift lever) from drive to park. This may be due to a time delay with the brake shift interlock (BSI) pin retraction.
ACTION: To service, replace the BSI switch. Refer to the following Service Procedure.
SERVICE PROCEDURE
  1. Remove the two (2) fasteners supporting the instrument panel knee bolster from below the steering column and remove the cover (Figure 1).

    tb7934b.gif
    Figure 1 - Article 04-22-12

  2. Remove the three (3) fasteners supporting the steering column lower shroud and remove the cover (Figure 2).

    tb7935b.gif
    Figure 2 - Article 04-22-12

  3. Remove the three (3) wiring bundle carrier fasteners from the bottom of the steering column to allow movement while removing the BSI switch. It may be necessary to release the connectors from the multifunction switch (Figure 3).

    tb7936b.gif
    Figure 3 - Article 04-22-12

  4. Remove the BSI fasteners (T-30 on the side and T-20 on the bottom) (Figure 4).

    tb7938a.gif
    Figure 4 - Article 04-22-12

  5. Pull the BSI tab on the bottom of the column downward to help free the BSI from the column housing.
  6. Break the two (2) side tabs off the BSI by the white wiring connector (Figure 5).

    tb7940a.gif
    Figure 5 - Article 04-22-12

  7. Push the locking tab on the white connector towards the wiring to release the connector from the BSI. Be careful not to damage the connector or wiring. If the connector does not free easily, a very small flat screwdriver may be used to help lift the locking tab (Figure 6).

    tb7941a.gif
    Figure 6 - Article 04-22-12

  8. Connect the wiring to the new BSI. Ensure all clips are fully engaged to prevent the connector from pulling free.
  9. Reinstall the BSI onto the steering column and reinstall fasteners (Figure 7).

    tb7942a.gif
    Figure 7 - Article 04-22-12

  10. Check BSI function. With the key in the accessories or run position, press the brake pedal. The BSI pin should retract on brake application, and spring up one (1) second after releasing the brake pedal. Repeat several times.
  11. Reinstall fasteners to connect wiring bundle carrier to the steering column. Make sure all connections to the multifunction switch unit are secured properly.
  12. Reassemble steering column in reverse order. Ensure rubber gap hider around shift lever is properly seated on the shroud.
  13. Cycle the shift lever from park to drive and drive back to park several times to verify improved shift effort.

you may need a second person to "rock" the vehicle if its just jammed, or the shift interlock may be keeping it from shifting out of park. do the brake lights work? there should be a procedure to bypass it in emergencies in the owners manual.
