Similar to what lots of folks have had w/ the 2012 xmission. My mechanic says it is a known issue with valve body quality in the xmission. My problem didn't start until sometime > 100K, which was post warranty. If you still have warranty coverage, get it documented by the dealer and you can probably make a case for new xmission if it gets worse even if you are > 100K at that point.
I found that I could almost make it happen by driving very easily through the 1 --> 2 shift, then just as the 2 --> 3 shift happens, ease up on gas a little bit (e.g. unload the xmission synchronizer) and it would almost certainly see a higher RPM 'slip' as it hunts for 3rd gear. If you had that same condition occur while loaded, that is where the 'bang' and the hard shift comes into play. Try it - you may be able to get good enough to demo it to the dealership. I really wish my problem had started at < 100K. Hyundai knows about it for sure, but once you hit 100K all bets are off!
I'm well past 100k now and although I had it documented prior to 100k; 99,560 to be exact when I brought it in for a trans flush/fill. They wanted me to pay $125 for a "transmission diagnosis". Needless to say that particular day the car was shifting smooth as butter and I told them this. Of course, for them to make a determination, they had to actually drive the car and witness it for themselves, even after showing them a video that I had shot while the trans was acting up.
So now, I wait and hopefully the trans lasts for a while. I can deal with the issue for now as long as the car remains reliable.
