    2002 Trailblazer
    Drove it from san antonio to phoenix
    105000 miles on her

    She has done me well since i got her a year ago but a month or so ago it started being dumb every so often, it will start fine but when i go to shift its stuck in park so i have to use the shift override gets kinda annoying any suggestions? I am pretty sure it has something to do with the brake electric system but i cant figure it out. Got my Chevy Parts Online too.

    2002 Trailblazer won't shift out of park

    When you step on the brakes, you're supposed to hear a "click" ... that's the shift-brake-interlock, and it's designed to keep you from shifting out of park without pressing the brake. It's probably starting to fail, but this has happened to me before a few times and I got under the dash to make certain that everything was tight and it's been fine since.

    Of course you can do the manual shift release, which there is always one in every vehicle I beleive, and in the Trailblazer that's on a flap on the steering column, but check your manual for the exact location.

    I'd first look to get the 'A/T Shift Lock Control Solenoid' replaced for this, go to your local GM parts, chevy parts house and see what it will cost, I think it's fairly easy job to do yourself. You might also want to check the chevy brake light switch to make sure that's working well too.

    I knew there was a solenoid but didnt think it was it since it doesnt happen all the time. Ill give her a try. thanks again!

    Actually its much more common for the brake switch to fail than the solenoid. (probably at a ration of 9-1 in my shop)

    Obviously it could be other things, like wiring or fuses, or strange brake light problems.

    First thing to check is look to see if the brake lights are working.
