Looking for some advice before I start throwing money at this.
Vehicle:
2020 Jeep Renegade Latitude 4WD
~49,000 miles
9-speed automatic transmission

A few days ago I was driving on the highway when I got both a “Service Transmission” message and a check engine light. The vehicle continued driving completely normally.
I stopped at AutoZone and their scanner pulled:
P1DB7 - Torque Converter Clutch Performance
What’s strange is:
The Service Transmission message eventually went away on its own.
The check engine light stayed on.
The Jeep drives completely normal.
No shuddering.
No harsh shifts.
No RPM flare that I’ve noticed.
No limp mode.
No transmission overheating warnings.
However, after paying closer attention, I’ve noticed the issue seems to happen only after 40+ minutes of highway driving. Around town I have zero problems.
The AutoZone employee thought it might be a sensor or software issue because there were no other transmission codes and the vehicle isn’t showing any obvious symptoms.
Questions:
Has anyone seen P1DB7 on a 2020 Renegade with the 9-speed transmission?
Did it end up being a software update/TCM reflash, a sensor, transmission fluid issue, or an actual torque converter problem?
Is it safe to keep driving while I diagnose it?
Is there a way to view torque converter slip data with a regular scan tool?
Any experiences or advice would be appreciated.
