Technically Naruto was able to use Ninshu, which makes what fans call "TNJ" technically a canonical power. After all, the entire point of Ninshu was to connect to other people.

Secondly, if Itachi can permanently Transcript abilities he would've transcripted Shisui's eye. Therefore, the least contradictory conclusion is that Transcripts only seal a limited amount of uses.
