I just did this repair, it wasn't too hard at all. Seems to be better so far. Will know in a week or so if its fixed for good or not.

Same thing has happened on my ‘22 Silverado Z71 RST. Started around 30k miles. I’ve been following this thread, for over a year now, thinking maybe GM would come up with a fix. My switch was initially intermittent, happening only occasionally, no pattern to it…I pulled the cover off the steering column, bent the metal tab just enough to make more contact with the switch (careful not to break the plastic lugs holding it in the frame. I had to super glue it back). Well, last week it started all over, 55k miles now. But now the switch won’t work at all. I’m not paying the dealer to troubleshoot an alert that tells me to put the truck in park.

So I cut and nutted the wires together.

Problem solved. Save yourself the hassle and money. Just don’t rely on your vehicle to tell you it’s not in park lol.

I’m not your mechanic.

For those curious, I did attach a pic of the numbers on the switch I cut off. If you can find the actual replacement, let me know.

Exactly the same problem [And Solution ] I had on my 19' GMC Elevation. GM has no solution to this problem short of changing the entire assembly. Pretty sad when a $10 part would cost you $400 +- through GM to get fixed.

I did the same, a year ago. Works great, Cost : $0

Same thing happened to my 2019 Trail Boss. I decided to take a cheap alternative than a jumper or buying a replacement part.

GM part numbers for the Automatic Transmission Control (micro switch not sold separately) for about $140.

84797128
84800776
85565585
85515701
86564191 (Most Current)

I detached the micro switch and used a zip tie in case I ever want to return it back to factory. Some people have had luck by bending the lever a bit to get it to work more efficiently. I figured it would fail again so a cheap zip tie worked fine for me. Then I tucked it neatly.
