Point taken. That definitely wasn’t my intention whatsoever and I apologize if it came across that way.

It’s ridiculous. Now if it was a recall, they’d get right on it! ?

UPDATE: I contacted GM last week - someone reached out to me today. We talked for quite a while. So tomorrow I’m taking it into a dealership not affiliated with the previous two. The GM rep is contacting them to let them know what exactly is going on. I’ll probably drive it with the tech tomorrow so the issues can be ‘replicated’. ??

My stepdad owned a dealership so I was raised and worked in that environment 20+ years. I did everything but sales & loved it! So I’ve been on both sides of the counter. I’m no expert but I’m not stupid. GM gave me a reference number - they said they’d contact the dealer and myself next week to figure something out.

Exactly! I’ve been to 2 dealerships - of course they can’t ‘replicate’ any of it. I could go to a third one or take a drive with the tech but why at this point. I contacted GM - someone will be in touch with me next week.

Honestly at this point, I don’t care. It’s just exhausting driving our Silverado. Only reason we passed on the Tundar was because of its MPG and towing capacity. The dealer today did a relearn but the shudder is still there.

Does the Duramax have the shudder?

Sorry for the long rant -- We have a '20 Silverado 1500LT (8-spd). Bought it w/16,000 miles on it on Aug 1. Hubby test drove it and I just did the financial stuff. A few days after we bought it, I drove it up to the store and noticed the awful shuddering starting @40mph and especially highway speed. Also, going over any kind of bump or groove in the road, it shakes horribly side-to-side. We had the tires rotated/balanced and an alignment. Didn't help. Took it to 2 dealerships and the first said they noticed a light shudder but no codes came up. Mentioned TSB 16-NA-019 but they didn't have a trans mechanic to work on it and referred us to the other dealership. Just picked it up today from the 2nd dealership. He said they test drove it and there's nothing loose in the suspension and he felt a light shudder but nothing abnormal. I asked him that when it's time for us to take it in for the regular trans service, if they swap it out with the Mobil 1 - he said that's what is in the truck already (it came with it from the factory). He said they started putting it into the 2019 Trucks from the factory. I call BS but whatever. I looked in the manual and it says it takes Dexron-Hp so I'd assume that's what was put in it in the factory. I hadn't heard about the 'Chevy shake" until I googled the shuddering. I noticed the comments about the trans fluid, torque convertor, driveshaft, etc. Very disappointed - we were excited about buying our first Chevy truck. That Tundra is looking pretty good right about now. I guess my question is to take it to a third Chevy dealer and try again and maybe go on the test drive with the mechanic - and demand that they swap the fluid. I'm so pissed off right now but mostly just disappointed. Kristy F
