Going to check out a CPO 2016 TLX V6 (SH-AWD) tomorrow. How and what should I be looking for with the transmission and any other issues?

Going to check out a 2016 TLX tomorrow and if everything goes alright, I'll probably try and leave with it tomorrow night. That said, I know the 2015 was plagued with transmission problems and while most say they haven't experienced it on 16+, I'm curious what I should still be on the lookout for. Laggy shifting? Slow to shift? I was hoping you guys might be able to tell me anything you might have experienced. This is the first Acura I've driven (Subaru, Toyota and VW before) so I'm excited to check one out. Any other things to keep my eyes out for would be greatly appreciated. Thanks!
