Got the truck back yesterday they did a fluid flush and a Filter replacement and told me to drive it for 200 miles to see if the shudder goes away. On my way in to work today I didn't feel it one time so my fingers are crossed.

Not yet I'm dropping it off tomorrow.

Dropping my 8 speed 6.2 off on Tuesday I've got 33,000 miles on it now. The shudder has gotten really bad once I hit 28k. The service rep said it's probably a tune update but reading these messages I hope I'm not jerked around. Sure does suck that after paying almost $60k for a truck this is such a common problem and no real solutions have been presented.

It has happened to me on occasion maybe 3 times over 25k miles. turned back on after one second so I didn't care

I agree and would like to know. I installed the Motofab kit last night and the bolts that came with the kit were too short the threads didn't even go into the nylon portion of the lock nut. I got some longer bolts today I'll swap out the shorties. What is everybody doing with the 1/2 shafts to get the bolts in from the top or are people just putting the bolt in the from the bottom and putting the nut on top?

Bought my truck new in December 2017 Sierra day one the drivers wiper was complete crap streak city. I contemplated going back to the dealer to complain that a $50k vehicle should have come like this but instead I just bought a set of Bosh Icon blades and have been pleased.

The link above no longer works I found this one for $60 https://gmtoolsandequipment.com/en-US/Pages/ItemDetail.aspx?SKU=EL-50448
