    New here, hopefully you guys can help! I have a 2003 Chevy Blazer 4wd automatic, ZR2. I am including a video. About 99% of the time, it won't shift out of park, unless I push out on this little white piece (as shown in video). If I push out that piece while stepping on the brake, I can shift out no problems and drive on like normal. It doesn't happen shifting from reverse to drive, or drive to neutral. Only once I put it into park. So, couple questions.

    1. What is the problem/part?
    2. Is it easy to do yourself?
    3. If the above answer is "yes", anyone have any how-to videos?

    Theres an easy answer and a not so easy one. That white piece is a solenoid that is part of the system. There should be a wire harness right next to it, check that harness for a broken wire. If there isnt a broken wire, it will be more difficult. There is a switch on the brake pedal. one on the trans, and a fuse that are all in communication to let you shift out of park. something could be bad with any of them.

    Sounds like some kind of faulty safety switch. Like squatchy said, it could be a broken wire. Maybe when you touch the white 'piece' you just happen to form a connection, letting you switch out of park

    Rocking that solenoid is probably a built in override. Its actually pretty common for console shifters, I had a grand prix that had the same problem. Too many moving parts in there and that wire harness is just kinda in there, its not really held in place
