2002 avalanche 1500 4x4 z71. Replaced key lock cylinder and case. Restored pass lock. Now shift lever stuck in park.

What can I do to free it?

Are you applying the brake? The vehicle won't shift out of park if the brake peddle is not depressed, there is a lock pin that prevents the shift from happening if the brake is not pushed down, you may have disconnected the power to this pin.

Yes I push hard. I also checked the solenoid. Seems to be ok. Can a ignition switch affect it?

in2pro

Yes it could if the pin is in a bind and unable to retract

I really appreciate your thoughts. This all started with replacing the ignition lock cylinder. After I reset passlock is when I found shifter stuck in park. I also forgot to mention that I replaced the brake switch to no avail. What pin are you referring to? I am going to check the shift interlock solenoid again. I didn't pull it yesterday just disconnected it thinking it should release. But got to thinking if plunger is stuck, that would not affect it. So I am diving in again!

try wiggling/turning the steering wheel while trying to get it out of Park.

I have tried that and I jacked the rear wheels up and rotated the wheels in case it was the transmission pawl. No luck.

When I say "pin" I am referring to the shift interlock. In all likelihood that is what is causing your problem, its either not getting power to disengage it or its wedge/stuck in. The brake peddle being depressed is what actives the retraction of the "pin" to allow the shift lever to move.

See if these help any, and no, the links in the document are not clickable as they reside on my PC....

Thanks for the schematics and troubleshooting guide In2pro. I thought that you were talking about the interlock shift but wanted to be sure. I am taking a break until next week when it warms up a bit. I will get back to you with the results.
