Same trans as 5.3, with a 6.2 in a 14-15 it will be the weakest link in the chain, pound on it with 35's and it will shit the bed. Don't get your idea the 16 is ugly, I like the wicked evil grin it has, like it is hiding something special but everyone has their own tastes so that's fine with me. Please drive a 14-15 with 6.2 and you won't have any doubts if it fits your needs, look for LTZ and High Country trucks because it will not be found in a LT or LS chassis.
