Stuck in park will not shift


Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. 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.


?€¢
The park/neutral position switch.

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. When the transmission is in the PARK position the contacts in the park/neutral position switch are closed. This allows current to flow through the switch to the automatic transmission shift lock control switch. The circuit continues through the normally-closed 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, locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to release. This allows the shift lever to move from the PARK position.
Park Lock Solenoid
The park lock solenoid is a safety device that prevents an inadvertent shift out of PARK when the key is in the OFF position. The key must be in the RUN position to release the park lock solenoid. The system consists of the park lock solenoid. With the ignition in the ON position, voltage is supplied to the park lock solenoid. The park lock solenoid energizes through a permanent ground unlocking the shift lever. With the ignition in the OFF or ACCY position the park lock solenoid de-energizes and locks the shift lever in the park position.
Shift Lever Does Not Move with Brake Pedal Depressed
DEFINITION: Transmission shift lever will not move out of the PARK position with the ignition ON and the brake pedal pressed.

Have 1996 Ford F250 that won't turn over. The truck is permantly in the on position. No matter what position the key was in the truck stayed in the on position. It doesn't go to off and will not turn...


Lock cylinder is not properly engaging the ignition switch. There is a pushrod from the end of the lock cylinder that moves the slider on the switch. Make sure the pushrod is properly connected to both the cylinder and the switch.

0900c15280047a11.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Fig. 1: Ignition switch assembly
If equipped with an air bag system, make certain to follow the recommended disarming procedure before, and rearming procedure after, repairs.
  1. Disconnect the negative battery cable and disable the air bag system, if equipped.
  2. Remove the column to instrument panel trim plates and attaching nuts.
  3. Lower the steering column and disconnect the shift indicator cable.
  4. Disconnect the ignition and dimmer switch wire connectors.

The steering column must be supported at all times to prevent damage.
  1. Remove the switch attaching screws and remove the dimmer switch followed by the ignition switch.

To install:
  1. Move the key lock to the LOCK position.
  2. Move the actuator rod hole in the switch to the LOCK position.
  3. Install the switch with the rod in the hole. Adjust the ignition switch as follows:
    1. 1990 - Place a 3/32 inch drill bit in the hole on the switch to lock the switch into position. Move the switch slider to the extreme left position then move the slider 1 detent to the right OFF LOCK position. Remove the drill bit.
    2. 1991-93 - Install the ignition switch in the LOCK position. Move the switch slider to the extreme right position and move the slider 1 detent to the left LOCK position. Depress switch mechanism slightly to insert a 3/32 inch drill bit into ignition switch.

  4. Position and reassemble the steering column in reverse of the disassembly following the proper coil centering procedure. Enable the air bag system, if equipped, as follows:
    1. Connect the yellow 2-way SIR harness connector located at the base of the steering column.
    2. Install the SIR fuse to the fuse block.
    3. Turn the ignition switch to RUN and verify the inflatable restraint indicator flashes 7-9 times and then turns off.

Gears locked up on P (park)


Sounds like the shift lock is not working. Maybe something was put together wrong with the ignition switch.
