If you get the gas V6 you must get the 8 speed tranny. BAD=BAD. Look up the Chevy 8 speed Transmission "shutter", mine dident start the shutter till 800 miles and it quiet for about 400 every time they changed the fluid.
Its been going on since 2015 and they still cant fix it. They had my 2018 67 days total. 2 new fluid types, 1 new tork convener and a new transmission, 2nd worse than the first. After a long and time consuming BBB fight they replaced it with a 2020 4 cyilnder with the 6 speed. 6 speed tranny works fine but 4 cyl. is just way under powered. I just drive it back and forth to my public job. Toyota Tundra does all the farm work. I think the diesel has the 6 speed tranny so stay with it.
I chose a badass Summit White with black hood scoop in the V-6 Model.
