About three weeks ago I traded in my two year old 2017 Z71 LT with a 5.3 6 speed for a 2019 Z71 LTZ 6.2 10 speed. A few thoughts...First I really like and liked both trucks. But the 6.2 and 10 speed makes up for the things I didn't like about the old one. The 6 speed transmission always seemed to be hunting to gear down here in the Mtns. of PA, plus clunk downshifting during slowing down. It never seemed to be in the right gear going slow turning onto a road to go up a hill. Then kinda bogging and downshifting hard to make up for it to get going. The lack of spunk and weak feeling tranny in my opinion led me to getting rid of it. The 6.2 and 10 speed solved all the annoyances that I didn't like about my old truck. Both trucks drive great and are nice and quiet. Although the seats in the 2019 do feel a little short for a tall guy compared to the 2017. One other thing I noticed that is different and kind of irritating, is the fog light button should be on the headlight knob instead of the exterior mirror lighting button. Minor annoyance that takes a couple weeks to get used to.
