Cannot depress button on gearshift to shift out of park. I am pushing on the brake peddle

its your neutral safety switch

What is the year/make/model and engine size of your vehicle? Do you have an automatic or manual transmission? If automatic, is the gearshift locked in Park? If so, there is likely a problem with the brake switch (located at the top of the brake pedal near the firewall), or with the shift solenoid. As a safety feature, this solenoid has been installed for many years, and it is tied to the brake switch, meaning that the brake pedal must be depressed before the car can be shifted out of park. If the brake switch goes bad, you will not be able to move the shift lever.

Someone replaced a dual-filament brake lamp bulb with a 'single' filament bulb.

The brake rlease switch for the gearshift might need adjusted-replaced or the shifter itself might need adjusted

There may be a malfunction in the shift interlock sys.
This sys. keeps the shift from being moved from park
unless the brake peddle is depressed. There are 5 fuse's, directly or indirectly related to the interlock system. Fuse #6 15amp in the fuse box under the hood on the left side. The next 4 are in the fuse box
behind the left side of the dash. Fuse #3 15amp/fuse
#18 15amp/fuse #16 20amp and fuse #4 15amp.
Check these first, before you move on to the brake
light switch, under the dash at the brake peddle.
And the shift lock solenoid, under the console left of
the shift lever. Hope this helps.

ck brake switch,,shifter will not move,,if brake switch on brake peddle does not activate it ,

The park lock-out solenoid is bad. It locks the shifter in park until you depress the brake pedal. You can remove the console and replace this solenoid or defeat it with a zip-tie.

Check your shift interlock switch on the brake pedal. If it is out of alignment or has failed the shifter will not unlock to enable a gear selection.

Also - a fuse may be blown, or you may have a taillight out.

You can manually unlock it in emergency situations.

Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Locate the access cover plate to
the brake-shift interlock override. It
is located on the underside of the
steering column.
3. Rotate the access panel
(counterclockwise) with a flat head
screw driver until it is lined up to
the access hole in the open position.
4. Insert a tool (or screw driver) into the access hole to override the
brake-shift interlock. Apply the brake and shift into Neutral.
5. Return the cover plate (rotate
clockwise) to the closed position.
Start the vehicle.

If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to Fuses and relays in the Roadside
emergencies chapter.

It might just be a fuse. Check to see if your brake lights light up when you step on the brake with the key on. If not it is probably just a fuse.

Chances are you're parked on a hill. You need someone to push on the car to take the pressure off the parking pin in the transmission. The other possible problem is there is a solenoid the won't release the gear shifter until the brake pedal is depressed. If you are pushing the brake pedal before trying the gear shift there is a malfunction in this system. This is not as easy to fix. If you aren't mechanically inclined I recomend taking that to a mechanic. If you are so inclined let me know and I can help guide you thru the steps.
