What shake issue are you speaking of?
Are you talking of the TCC shudder?
If so, there is a TSB that covers that with a transmission fluid change.

It was 60-70mph shakes

Sounds like pinion angle and tire problems. For me, I've got my pinion pointed .5* lower than the t-case and then I've locked that in with a set of RC traction bars. It's shocking how sensitive this truck has been to pinion angle. If it's off by just a couple degrees you'll get vibrations at different speeds. When mine was 1.5 degrees lower (stock setup) than the tcase it vibrated pretty bad between 57-65.

Did it solve it ? Thanks

Near as I can tell it did. The only speed sensitive vibrations I get are between 78-84 MPH and  I think that's driveshaft related now, but still could be my crappy tires (lots of weight to balance is usually indicative of a bad tire). All in all, it seems like these frames are very sensitive to NVH. Everything comes together. Can't say 100% it's because I corrected the pinion angle but it certainly played a role. Next up for me is a better front suspension setup - then tires. I imagine by then I'll be very happy. 

 

Far cry from when I picked it up in Houston and drove 4 hours home. It was pretty bad and made me regret my purchase. Road-force balance the tires, new/slightly better struts and shocks, and Roadmaster active suspension combined with traction bars, and biggest of all - custom tuning have made it drive a lot different.

Glad that you are almost there and some what better , mine is in the dealer now for diagnostics, all of these post I’m reading watching makes me think that I may have to go couple of times back fort and fight with the dealer my biggest fear Is they gona tell me what everyone already knows step one trans oil flush with mobil 1, step 2 force balance ,step 3 drive shaft balance m, step 4 new wheels tires , I maybe over thinking it ,  I’m hoping it gets fixed. As I don’t have the recourse with time and money out of pocket. I have power train warranty October 2022. 
 

note: I have not Owned a pick up truck before 

Nor bought a car in a while All I know is I wanted a pick up for while I waited saved up for 15 years to afford it now this ... smh

Welcome to this forum!   The Chevy shake story is covered extensively in this forum and you will find a lot of potential causes and solutions to the shake.  .  I have experienced a few shakers (not all GM) in my life and the cause has always been a tire/wheel related issue.  Your problem can be as simple as a wheel weight falling off.  Don't overthink the issue or start replacing parts until you've tried the simple fixes.

thats exactly what mine was. i had a wheel out of balance.

Another possible fix is to move the tire; front to back or can also try L to R after that. Does your truck have a lift kit installed or is it stock? What make of tires? what wheels? factory or after market?
