Tremec TKX first cuts

DC Dart can you give us a follow up on the TKX trans shift quality after you get your car up and running and drive it for a few thousand miles. My experience with Tremec transmissions namely the TR6060 6 spd is the synchro's are absolute junk, real notchy and feels like the synchro's are not working right from the get go. I am on my second one in my 2012 Challenger and will never own another one. Now Tremec said they fixed the problem in the TKX but they said the same thing about the TR6060. I am hoping they got it right on your TKX trans. because Tremec says the TKX can be shifted at 7000+ rpms and I truly do not think a TR6060 will shift that high. I shift both my TR6060 at 6500 and they both shift under extreme protest.
