I’m guessing you’re dealing with torque converter shudder and not the dreaded Chevy Shake.  Ask your dealer to perform the TSB which is complete flush, filter change, refill with new type fluid and reflash.  Appears to fix most torque converter shudder problems.   

 

 Its booked in next week to have the eps reflast, so will get them to look at it again.

Video of what my truck is doing. So if you watch the rpm, it sorta blips. everytime it does that, you feel a shake. You can kinda hear everything rattle a bit. Cruise control is on, but doesnt have to be for it to do it. Seems almost like the tc slipping no?

just to  add, I dropped off the truck this afternoon and they gave me a 2019 Canyon. Night and day difference in driving that than my 2018 truck. Mechanic said to "be patient" then later clarified that they had a couple of Sierra's in for the transmission issue. We'll see what happens. I did ask about about the F150 on the lot

Doesnt matter for me. I can run it in M7 and it still does it.

Not to bum you out, but I went through the same paces to include a new TC.  Still shudders:-(

Hello all, 

 

1st post for me, I have been reading the 800+ page saga of the Rear Vibration issue and appreciate ALL of the time and patience everyone has spent posting on here for others to read/learn/use. 

 

I have a 2017 GMC Sierra 1500 Reg Cab Long Bed that has the vibration issue.

 

 

Its currently on its 3rd trip to the dealer as of today. My Service Manager told me that GM is aware of the issue and that for many it is a tire issue. He said the Specs for this series of trucks is very slim for the road force variation tolerance. He said that it calls for under 15 lbs or less and only certain manufacturers of tires can fit these specs. They are replacing my 20'' tires with Bridgestones today and will do the road force on all of them. He also said that with the long bed I will notice more road inadequacies than the short beds. I asked him if he thought Air ride would help and he said he would ask around about it and then I also asked if putting Bilstein 5100's on the rear would also help. He thought it already had them on it but another mechanic clarified they use the Rancho's. 

 

I've done a LOT of research on this issue and one of GM's responses was "Suspension components and calibration will NOT provide a ‘sofa-on-wheels’ type of ride, and will NOT eliminate tire/wheel, propshaft, rear axle related inputs/disturbances; they are designed specifically to address the rough, harsh rough/harsh/stiff ride concern."

 

I also watched some of GM's training video's for the Hunter Eng video's as its possible some of the dealerships have been doing the road force without doing the force matching: 

 

 

For the record I am not an expert or a certified technician, Just an idiot with a shaky truck that wants to get it repaired. 

 

One of the guys at the dealership said I could always throw 2 sandbags in the back of the truck and that may help, my response: Is that under warranty and what's the GM part number for the Sandbag? 

 

Will post when I hear back from them and have fingers crossed for a smoother truck on that first drive!
