You left the 2 internal pulse generators as possibles, and I wonder if those are what are responsible for triggering the P0772,3 codes that indicate an incorrect ratio, meaning that they are measuring the differences and are working fine?

I would discount those items being likely causes, and take them off your list of things to worry about.
Pulse generators provide an on-off signal, so they won't measure wrong, they will work or not.
As a general comment, you are focusing on electrical components, likely because of the error messages. However, the problem is on downshift, and the same electrical components are used for other shifts. It suggests that you have a mechanical/hydraulic problem. It appears to be an electrical-related item because the module monitors electrical circuits, but those are more likely to be symptoms than causes. All in my opinion.
