Little late to the conversation here, but does this apply to the 2014-2015 5.3 issue where it feels like it kind of slips/slams into gear when just easing around maybe 1st to 2nd gear? It's not very often but annoying. Took it to dealer with about 5k miles when she was still under warranty and of course that was a wasted trip. At 110k now and saw a video about the TSB etc. Anyone have input? Thanks
