Any other ideas other than the fluid level to get shift interlock out of park?

Brake switch, shift interlock solenoid or bad transmission range selector. Shift interlock won't let you shift out of park unless your foot is on the brake. So brake pedal starts the cycle. Next, the vehicle has to be in either park or neutral. So power flows from the brake switch through the transmission range selector which then sends power to the shift interlock solenoid which moves a pin out of the way, allowing you to shift out of park.

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 ?
Visually inspect for obvious signs of mechanical and electrical damage; refer to the following chart:

Shift Interlock System A brake/shifter interlock system consists of the following:

• ignition switch (11572)
• brake pedal stoplight switch (13480)
• brake shift interlock module
• brake shift interlock solenoid assembly (attached to key interlock assembly)
• necessary wiring

On floor-shift vehicles, the ignition/shifter interlock cable (3F719):

• locks the floor shift transaxle range selector lever in the PARK position when the ignition switch is in the LOCK position.
• requires the floor shift transaxle range selector lever to be in the PARK position to turn the ignition switch to the LOCK position.

Shift Interlock System
The shift interlock system prevents a shift out of PARK unless the brake pedal is depressed. The shift interlock system has a shift lock actuator mounted on the floor shifter assembly. If the ignition switch is in the RUN position, the shift actuator will allow the shifter to be moved out of PARK only when the brake pedal is pressed.
Electroniclly controlled !

Condition Possible Sources Action

• The shift interlock system does not release or lock correctly

• Fuse in battery junction box (BJB)

• Check fuses.

• Brake pedal position (BPP) switch

• CHECK the BPP switch. REFER to Section 206-09 .

• Floor shifter wiring and/or connectors
• Transmission selector lever
• Ignition system

• Go To Pinpoint Test A .

Maybe your shift linkage. If it is hard to shift all together, check fluid level. It may also need the trans oil changed

Shift Interlock System An ignition/shifter interlock mechanism is installed to prevent shifting the transaxle out of the PARK position unless the ignition switch is rotated to RUN and the brake pedal is applied. The floor shift interlock system consists of:

• an actuator assembly integral to the ignition/shifter interlock cable assembly.
• a bracket retaining the actuator.
• the necessary wiring.

The solenoid is energized when the ignition switch is turned to the RUN position, locking the transaxle range selector lever in the PARK position. When the brake pedal is applied and the stoplight switch (13480) is activated, the ignition/shifter interlock actuator is deactivated and the transaxle range selector lever can be moved out of the PARK position.

Shift Interlock System
The shift interlock system prevents the shifting from PARK unless the brake pedal (2455) is depressed. The shift interlock system consists of a shift lock actuator (3Z719) mounted at the base of the steering column tube (3514). If the ignition switch (11572) is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.

Thier is also the shift lock actuator ! plus wiring . You have a short to ground on that circuit . Do you know how to Find a short ? videos on youtube .
None of the power windows work ? Check for broken wires inside the rubber boot from the body to drivers door !
