In regards to the 8 or 10 speed trans option my real world expirience. My 2015 Silverado had the 6.2/8 speed combo. Bought it new. In the winter when it was cold out and the truck was cold the 1-2 and 2-3 shifts were always harsh until the truck warmed up. And sometimes cold or warm the down shift as you came up to a stop light was harsh. Had it back to the dealership for updated programming a few times. Never really fixed the issue. Never left me anywhere but annoying. Over on LS1tech.com the 8 speed gets no love at all.
So my current 2020 Silverado with the 6.2/10 speed combo is sweet. In the normal mode the trans shifts like butter. If you go to the sport mode the shifts are a bit more sharp and move up on the rpm a bit.
I could be wrong but I'm thinking all direct injection 5.3/6.2's have VVT and DOD.
