My wife’s 08 Z51 auto had the plastic clip fall apart on the transmission cables a couple years back so I replaced with aftermarket ones. Just somewhat recently on occasion the car won’t shift. The most recent after a short run stopped at a gas station and it wouldn’t come out of park, I did a little rocking of the car and shifted as it should. I’ve noticed on other auto cars they have an over ride on the console if the break pedal doesn’t activate to allow the trans to shift but I didn’t see one here. Any thoughts on what to check or watch for? I don’t think the cable has any adjustment?
thx

Good luck.

It's caused by a weakened microswitch that will not send the signal to the solenoid to release the shifter locking pawl. It's really a shame that GM decided not to put an override like other GM vehicles have.
Regardless, most on here with autos have just tied back the locking pawl, or ran a wire loop back to the console under the armrest to pull to release the locking pawl if needed.
I'm sure that this is in the link provided, but if not, PM me your e-mail address and I can send you the info in PDF format.
