I have a 2017 1500 silverado LT with 2000 miles. Truck is miserable to drive. Always feels like there is a engine miss and random transmission shudder. Happens specifically when under light acceleration. Example: 40 miles an hour and light acceleration. You feel shudder in seat of your pants and engine stumbles to accelerate. Also, at a stop, I held brake down(Traction Control was off) and brought RPM's to 1500. Under this load engine missed.

 

Brought to dealer and they say nothing is wrong with it! Any help is appreciated.

Mine is a 2015 Denali. I have the shudder like running over warning bumps in the road but not as pronounced. I'm taking it in Thursday for a new Torque Converter. I had to wait several weeks for one to show up. I don't know about the low acceleration though, mine runs like a raped ape.

UPDATE:

Picked up the 2017 Chev Silverado today. Been at local dealer all week. Results are pathetic and ridiculous! Drivers side front door excessive wind noise( Have to turn up radio to mask it) Per Chevrolet, nothing wrong with it. Normal and within specs. Shuddering during light acceleration. Stumbles between gears. No power Per Chevrolet, Nothing wrong with it. Within their specs! Clunking and shifting rear end under acceleration and deceleration. Per Chevrolet, Real leaf springs were not torqued (tightened) from factory. Rear drive shaft removed and yoke greased with synthetic grease. Result, still does it. Manager tells me off the record, they are having issues but he cannot do anything as Chevrolet has no fixes. He also tells me that the prblomatic Active Fuel Management system like on my truck is also used on $90,000.00 Corvettes and he is having complaints . They are removing the Transmissions and replacing the Torque converters.Final thoughts: It is a miserable vehicle to drive. I put 40 to 45,000 miles a year on these trucks.Chevy should be ashamed.

How did it work out?

The 8 speed is providing plenty of issues to many people, you are not alone. The symptoms you describe do sound worrisome. I.E it doesn't sound like normal transmission break in period hiccups. And you have 2000 miles already, so you should be through the worst already.

I had the wrong day marked down. I take it in this coming Wednesday. I'll report back when they are done and I've had a chance to test drive it.

If they plug up there little puter up at most dealerships and it says no codes they have no clue what to do......... part laziness and part ignorance. Do you have another dealer close by that you can take it to? Sometimes though rare you CAN find some intelligent life even at a dealership Good Luck

Here is a little update. I can minimize the wind noise by lowering the drivers front glass just slightly. Again Chevy says this is normal for the wind noise.

Picked up my 15 year old nephew Saturday for his first ride in the truck. Keep in mind he has yet to drive a vehicle and I never said a word to him. As we are going down the road after a few miles he says" Uncle Joe, What is wrong with this truck"? I asked him what he meant, he said" It's jumping and I feel it in the seat". All I could do is laugh and shake my head.

 

If I put the truck in Tow Mode, some of the drivability issues go away.

Took to my third dealer. They finally listened to me and removed the transmission and torque convertor. As I suspected through 20 years of service experience that was the problem. Torque Convertor was eating itself and pump was failing. Bell Housing was replaced with new pump as comes together. Seem s fine now. Chevrolet would not replace the whole transmission. Just flushed and replaced fluid with new parts. I suspect failure in future.

      2027 Chevrolet Silverado: Official Discussion

      By Zane · Posted

      It's official. Chevy pulled the covers off the next-gen 2027 Silverado 1500, and we got the first official look.   Full breakdown here: https://www.gm-trucks.com/2027-chevrolet-silverado-official-first-look-specs/   The quick hits: LT is dead. The new core trim is just called "Silverado." Two new V8s, a 5.7L and a 6.6L. No horsepower or torque numbers yet. The 2.7 TurboMax finally gets the 10-speed. ZR2 moves to standard 35s with front and rear lockers. Over 60 inches of dash display on ZR2 and High Country, passenger screen included. Seven trims, three lifted from the factory: ZR2, Trail Boss, and a new Custom Trail Boss.   So let's get into it: 5.7 and 6.6 instead of holding out for a 6.7. Right call? Killing the LT name after all these years: bold, or a mistake? Does the new look land for you, or is it too safe? No power numbers at reveal. Smart tease, or frustrating? What are you ordering on day one?   Drop your first impressions below.

      LOL west coast they need to see what the midwest actually has.  We have been holding at 2.99 for a few weeks now.  Even by work they have come down to 3.02 for the past week.

      Diesel or gas?  The 37s will obviously, drastically reduce mpg, but the gasser will take a bigger hit to mpg, and power.  Rough guess, but I'd estimate at least a  2mpg hit on the diesel, and up to 4on the gasser. Maybe more.    I wouldn't sweat a gear change on a duramax at all, and unlikely on the gasser either. You're obviously not concerned with acceleration or towing, and the 10spd will find itself in the right gear without much hunting, if any.    If towing, mpg and acceleration are a concern, you're doing the wrong mods.  Either leave it alone, or do the lift/tires and let the chips fall where they may.

      OCI, not when but why?

      By Grumpy Bear · Posted

      I understand. It is disturbing to think a manufacture asks so much and gives so little in engineering support. This is not a GM issues, this is a greed issue and one the ALL practice.    My intent was not to remove the wind from anyone's sail but rather to point out the areas deficient so that they can be discussed with improvements the goal. But to do that you have to know the truth and what that truth is.    The commercial interest are honed in on a few select issues in which they control all the variables and are not forthcoming in the least with their customers about the details. Failure is the only thing that drives these people to improvement. One way not to fail it to manage public "expectations". The set a bar they can clear and put their thumbs under the suspenders with chest puffed.... Only the internal data tells the story fully. As we don't have access to that for decades then we have to generate it ourselves. UOA's with data that matters.

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.
