Be somebody here that knows for sure, my 2016 has steel cyl sleeves in the 5.0 v-8 . I have heard they no longer do they are some kinda wonder coated aluminum. 18 or 19. The f series in 17 went to a10spd auto tyranny instead of the 6 mine has. I remember looking at a 17 and asking the sales guy what the axle ratio was and he said" don't matter it's a 10 spd" well does to me and that's why mine is 3.73 ratio.
