Gear shifter is not moving when u press on break

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

This is often a switch located on the brake pedal lever. The car requires you to press the Brake pedal before shiftting out of Park. You lose the signal when a foot hits or breaks this part. Look under the dash for the part and fix it.

follow the steps . God bless you
Instructions

1. • 1 Start the engine. Press firmly on the brake while wiggling the shifter from side to side.
     
   • 2 Remove the console surrounding the shifter. It is usually very easy although you may need to use the screwdriver to lift an edge or remove a clip
     
   • 3 Look inside the shifter mechanism for any sticky substance. Often when drinks are spilled on the console they seep down into the shifter mechanism and make the interlock solenoid sticky, meaning that it sticks closed when you press the brake and the car won't come out of park.
     
   • 4 Remove any sticky substance with the alcohol. Start the engine, press the brake and try to move the shifter out of park. If it still does not move then there may be another issue with the interlock.
     
   • 5 Examine the shifter for a release button that will allow you to move the vehicle out of park so it can be taken to a repair shop. It is usually hidden under a small flap or cover that will have to be lifted with a small screwdriver.
     

you will have to press the over ride button to unlock the shifter

there is a brake/shifter inter-lock system (u have to press the brake to remove shifter from park) motor is out

have the shift lock interlock solenoid checked out

The BTSI (Brake Transmission Shift Interlock) has a small spring retainer on the park safety. A small plastic tab breaks & releases the spring. This requires the shifter to be disassembled in order to be repaired.

Repaired mine Sunday May 1st and can provide detailed instructions if desired.

If you are lucky, your brake interlock is the only problem. There is a bypass switch located beside the gear selector. Remove the small "cubby" bin located next to the gear shift by simply lifting up to remove. You will note a small access port and a pink button contained therein. Press the pink button to override the brake interlock.

If you still cannot shift into park, then the shifter must be removed for the spring repair. Even if yours is still under warranty, you will get another shifter that will eventually fail due to poor engineering.

Please let me know if you would like my assistance.

You probably need to figure out the problem with the shifter. It has to think it's securely in Park before it will release the key. Try shoving forward on the shift lever while it's in Park as you try to remove the key.

SHIFTER LOCKED IN PLACE

1. Remove the instrument panel cover below the steering column, then remove the steering column shrouds to gain access to the brake transmission shift interlock (BTSI) solenoid. The solenoid is part of the interlock cable assembly.
2. Disconnect the wire connector from the rear of the BTSI solenoid.
3. Insert the ignition key and turn it to the ON position.
4. With the brakes applied, try moving the shifter out of the PARK position.

• If the lever now moves freely in and out of PARK, perform the Circuit Test below.
• If the shift lever still does not move from the PARK position, remove the BTSI solenoid from the shift lever assembly. If the shift lever now moves freely in and out of the park position, the BTSI solenoid is faulty and the interlock cable must be replaced. If the shift lever still does not move from the park position, the problem is in the shift lever assembly or the ignition interlock cassette
