Yes, I'll be watching this one close, as the 139 transmission has always been one of its jewels of design that solidly elevated it over the "weaker" 212/412 transmission. Plus the coveted "30 min run dry" halo.
High transmission temps are not uncommon in extended hovering in hot climates, but they come back down at lower power settings and better airflow in cruise. So something odd here with just high temp in cruise followed by "I'm about to self-destruct" transmission noises. No mention of pressure, chips, but early days before maintenance records/HUMS are known.
Anything from Leonardo? Bad year for 139's, but like the 92 the type most used will have the most incidents.
