Least problems? 18+ with 5.3 or 6.2?

[lbenson]

I got 175k out of the 8L90 in my 2015 Yukon with the 6.2L. Now have a 2018 with the 6.2L and the 10 speed with 82k miles and no issues with the transmission. Engine had a little piston slap that was fixed by having two bolts tightened in it at 80k. I would avoid anything with the 6 speed (2016+, when GM axed the 100k/5 year powertrain warranty for 60k/5 year). Only have heard of issues with those. My Uncle's 6 speed in his 2016 Suburban blew at 79k. But with 70k on the '14 I would keep that and drive it forever. My buddy had a 2009 Escalade that went to 282k when he threw a rod through the engine block (Treated it too much like a race truck in the end!)
