Had my 2019 AT4 with 6.2 since Sep 2019. Major reason for 6.2 was it was the only way to get 10 speed tranny on 2019 models. I had the 8 speed in my 2015 6.2 SLT..the tranny was crap, one of the many reasons I no heartburn with trading it. I have just over 10k miles combination rural/city/highway. Getting average of 18-19 mpg. Get a little better with highway trips..20-22 mpg. 24.5 is best mpg I have gotten, but it doesn't take many hills to pull that average down.

Tried and Tried. Diode will not seat in fog light side. will go in High beam side all day long. Have broken all four diodes I had. I even trimmed the end. Tried with and without pliers. Tried with brown plug installed and removed. Mines a 2015 Sierra SLT. Guess this just isn't go to happen. I'm afraid if I mess with this connector anymore I'll screw up some of other connections. This sux, because with Hi beams on(which aren't that great anyway, even after new german bulbs and reprogramming of voltage at dealer) you loose all the extra light close in that the fogs provide. What a crappy set up for a 50K+ truck..
