AC crapped out, Transmission shudder UPDATE_4


Recommended Posts

Posted

UPDATE: Link for the transmission shudder issue from GM techlink publication. 

https://gm-techlink.com/?p=11127

 

Well its been only four months and 2,300 miles and I'm already at the dealership service department with two major issues.

1) AC stopped blowing cold air a few days ago, WTF!

2) I've have the infamous 8-speed transmission shudder from takeoff to second gear since day one.

 

Here's the news I got from the service department today:

The AC system is leaking at the evaporator and the console and the entire dash will have to be removed to replace the evaporator coil. 

For the transmission issue, they have a TSB that has them flushing out the transmission and Torque Converter and replacing with a Mobil 1 product (was hoping for a software update but no luck there).

 

Best part (sarcasm here) is they have asked me to take back possession of the truck until July 9th before they can get to both issues!

I cannot imagine the amount of broken plastic clips I'm going to wind up with once they get the dash back in. 

 

Really GM!!!

Oh my ache'n ass!

More to follow...

Bill.

Wow, sorry to hear that Bill.  That's crazy.. Can't you leave truck and get a loaner? Tell them you need A/C. A good service dept. Would do that.

That's terrible.  Especially on a brand-new truck!  Apparently, GM has no quality assurance methods now whatsoever, except to pump out vehicles as fast as they can and let us beta-test it for them.  Best of luck on the repairs.

Beta test would mean that when we find the problems they would fix them, let's face it this ac problem goes all the way back to the 2014 model years and the 8 speed trans shudder to the 2016 model year. Safe to say they will never fix these issues and everyone here will more then likely eventually have to deal with it. My best advice i can give is if you plan to keep this truck past 3 years and own it, you would be a fool to not buy an extended warranty with what these things cost to fix today.

2-3x my AC has not blown cold when I start the truck. (I have an RST just like you, OP). However, it always starts cooling whenever I turn the AC off, then back on, and after I start driving the truck. No major issues yet, thankfully. 

 

I'm closing in on 3000 miles, and my A8 has really tamed a LOT. I did have a super hard shift from 1-2 after reversing out of a parking spot 10 days ago. Otherwise, the shifting has gotten a lot better. 

 

I'm about to go in for my first oil change at 3K, so I am going to have them do the torque converter flush via the TSB on the A8, since I'll be in there for it. Otherwise, I'm pretty happy and many of the little issues I once noticed have either gone away or I stopped noticing them.

My Lt has had the shudder too since new, anyone got a copy of that TSB to take to my dealer? I know it’s a crap shoot but figure I may try it. 

 

6.2 10 speed looks better and better:/

So they want yo to drive in the summer months in your 'New" truck without Air Conditioning?  I wonder if they would do that.  Sorry to hear.  Unfortunately the bad dealers reflect on GM as a whole.  Manufacturers all need to be more focused on their dealers service departments quality.  Problem is they always take the dealers side. If you call any of them they always say they have to stand with the dealers decision.

UPDATE#2:

Stopped by the dealership shop and here is what my 2019 Silverado RST with 2,300 miles looks like when your replacing a defective Evaporator coil!

He is only 80% in, as the cross-beam support still needs to be removed before the HVAC box can come out. 

Hope for everybody else sake that this is not a systemic issue from the HVAC supplier. Maybe I'm the one in a million, should have played the lottery instead.  

So much for a new truck!!!

Bill.

    • Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....
    • Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!  
    • From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

    • True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
