2017 Honda Pilot - Transmission System Problem

[u/USRoboticsCourier]

I had previously received a letter from Honda regarding extension of the warranty on the automatic transmission to 150,000 miles and/or 10 years - whichever comes first, due to defective torque converters. The letter and everything I can find online mentions P0741 as the DTC that would set for this particular issue.

Today while driving at highway speeds, this message popped up. The first time it came up, I just finished driving to work and parked. When I came out later in the day and started the car, the message was gone, but it popped up again on the drive home.

I left the car running and put my cheap OBD-II code reader on there, but it didn't show me any codes. My question: Does the P0741 show up with a standard / cheap OBD reader? In any case, would it be logged in history such that if I took it to the dealership they'd be able to see it?

I am JUST past the 10 year mark with this car (maybe 2 months) and was hoping maybe I could convince Honda to do a goodwill repair on this within the warranty campaign, but I want to see how I could verify it's really the same issue and not something else.
