I have this problem too, so thank you for your posts. The problem had been intermittent, and annoying. And murphy’s law, it didn’t show up when I took the truck to the dealer for the repair; no codes

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.

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.

Fellas…this thread was extremely helpful! Been having this problem for about 3 weeks with my 2020 TB. Took it to the dealer only to find that I was out of warranty by 1600 miles. Went home, Fired up the computer to research the problem and eventually found this thread. Like most of y’all, I just now bypassed the micro switch and all is right with the world again. I doubt I’ll do anything more unless an unforeseen issue arises. Thanks again!

I have a 2021 Duramax Silverado and it started doing the same thing. The dealership wants about 850.00 dollars to put another shifter assembly.GM needs to have a recall on this.

      OCI, not when but why?

      By Chuck FB · Posted

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
