2014 7AT TCM and Valve body issues

The 1k price to fix is just for the part alone, me and my brother are more than capable of dropping and replacing the trans and have all the neccessary tools at our disposal. The hig issue is the TCM needing a reflash because if we get the part from nissan they will reflash once it's in the vehicle at probably a high cost, if I can do a plug and play then that would be easier and I have found some 7AT trans online with less miles for cheaper than the part cost. I will getting home in a month or so and will talk to the Nissan dealer about the reflash and getting the current TCM firmware for my vehicle to try to match it up as good as possible. Sorta off topic too but do you know of any sellers of sequential trans for our cars? I know quaife had one but it's not on their site anymore, or do you have any links to a thread about them/a build that uses one? End goal is a track orientated build so any insight in that would be great too. Thanks again
