Can't shift out of park. The button on the shifter is stuck. Using an extreme amount of pressure will cause it to depress. Then it may work fine for a while. but then, suddenly, can't shift out of park again.

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

If your vehicle is equipped with one,you've most likely got a defective brake/stop light switch.It will cause the brake lights to stay on continuously,not come on at all or prevent the shifter from moving out of park.If this switch is bad,it can cause just one of the symptoms above to occur or all of the symptoms above.So in otherwords,the brake lights can still be working just fine,but it can still cause the "shifter is stuck in park" issue you're having.However if your brake lights aren't working correctly,that's definitely a sign the switch is bad.

Hi, Check your brake lights, and other lights. On another truck of mine it did that and my brake lights were out so it locked the shifter until I fixed them. Hope you figure it out.

Check your brake lights, if the system doesn't get a brake lights on signal it will not release park, it is called the park lock system.

2002 chevy trailblazer on neutral mode, trailblazer can be pushed easily,but shifter is stuck on park. vehicle will start.the push button on shifter will not engage

Check fuses could be blown fuse. Or another possibility could be brake pedal switch. Brake pedal must be depressed to release shifter from park. Also try and check voltage at solenoid that releases the shifter from park. The solenoid should be located under the shifter, power should only be there when brake is depressed. If voltage is not present with or with out brake depressed than check fuse and switches before solenoid. If voltage is present with brake depressed and no action occurs at the solenoid than that definitely means it is bad. hope you get it fixed..

This car has a lock out device as all vehicles have. You need to depress the brake firmly to shift into gear as you may know. The solenoid that retracts the lock out for the shifting is at fault and needs to be replaced. You will see it if you remove the entire top of the shifting console

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

I fixed this on a friends car by cleaning the parts on the shifter. Button included. just use soap and water

I found it necessary to try two of the the fixes listed before I solved the problem. Here's what I learned, as it relates to my 2000 V70:

1. The lock button on the shifter WAS stuck in the depressed mode. So I squirted a bit of WD-40 and--presto! It was released. But my problem wasn't solved. On examining the button action a little more, I noticed it it wasn't FULLY freed. So, another squirt of WD-40 and a few more press/releases, and---PERFECT. BUT the problem was not solved.

2. I next tried to "lift" the "shift override" button using pliers with gentle-to-moderate pressure so as not to break the plastic. It did lift a little, but still no solution. So I squirted a bit of WD-40 into the space around the button and pushed the button several times to "work-in" the WD-40. No luck. In fact, the button seemed stuck in a depressed mode even more.

3. Finally, to the SOLUTION! Since I could no longer get a grip on the button, I introduced 2 thin-bladed knives to barely exposed opposing side surfaces and pried the switch-button up. Still, no luck, but going back to the pliers and gentle/moderate pressure, I was able to pull the button up, and----SUCCESS!!!!

Notes: I am surprised at how much travel there was in the button--a good 3/16" it seems.

I don't know what caused the button to seize in the depressed state. I never use it and I don't think that I've ever spilled anything on/in it. But its horizontal position just begs for this kind of problem.
