You don't mention what year of Mercury Grand Marquis but the owners
manual will explain what to do if the transmission gear shift lever will not
shift out of ( P / PARK ) with the brake pedal depressed ( it has what Ford
calls the " brake shift interlock " )
As of August 6 , 2012 you can still view the Mercury Grand Marquis owners
manual online ( back to the 1996 model ) at :

check your brake lights if they not worhing replace fuse or brake light switch
Sounds like a bad Brake Light Switch. It's located on the steering column.
Check the fuses- Shift interlock is the same circuit as brake lights. As a temporary measure - try to turn the key to 1st (unlock) position shift to neutral to start vehicle and then shift to Drive.
Just turn the key to the first position, ( not on ) and then you will be able to shift to neutral and start the car from there. Have the fuses checked and check the shifter sensor on the brake pedal.
shift lock is malfunctioning. you can bypass it there is a little "switch" on the side of your shifter for this purpose. that should help temporarily i believe there is a sensor to tell it when to shift out of park and that when this malfunctions you're stuck in park
My car will shift when i first go but wont shift after that help
Are you putting your foot on the brake ?
Probably a bad starter solenoid.
its broken !! take it to a mechanic
Align the shift indicator orreplace it. Your problem is strictly column mechanical.
Check the ignition coil on the Marquis. Check the crank sensor as well. One of these is probably bad.
SOMETIMES IF THE STEERING WHEEL IS LOCKED YOU WONT BE ABLE TO SHIFT OUT OF PARK. TRY JIGGERING THE STEERING WHEEL AROUND.
this happened to my 2006 Toyota highlander...look under hood...a piece of foam was stuck up under parking brake so it couldn't shift into park
The first and most often reason is that the OD is turned off.
Mercury changed the style of the Grand Marquis in 1995. 92-94 are compatible, 95-97 are compatible. You might be able to force it and figure out a way to get it to work, but it probably wont look good. My family have a 1993 and 1997 Marquis, and the front ends are different.
The shift lever cable may be damaged or out of adjustment.
im having the same problem now as we speak. i was told it was the shift solenoid located in the transmission.
The safety override switch is probably on. If not, then the motor or switch may be bad.
Hold your brake down while doing so.
The brake must be pressed to shift newer cars out of park, if the brake light circuit has an issue it can make it impossible to shift out of park. Make sure the brake lights work, fuses ect. If the system is not working many cars have an override for towing, check owners manual.
If the gear shift won't go into park on an automobile, the parking brake should be engaged and the vehicle turned off. This will prevent the vehicle from rolling away and potentially causing damage.
Sometimes when used to driving manual transmissions, we forget to press the brake pedal to release the safety so we can shift the automatic into gear. It will not shift out of park unless you do this.
The neutral safety switch, release switch, or brake switch is bad.
Change the brake switch located where the brake pedal is, a little above. Done!
push the little knob at the base of the shifter in front of it see if that will do it for you
