This debate is getting VERY useful !
Let me add a bit of poison, addressing a taboo topic:
Is there a known "super lubricant" ATF aditive that may help us on a preventive basis ?
I know and understand that manufacturers are adamantly against this. In fact cars are supposed to work with regular off the shelf stuff. (certificating aditives and their interactions with regular brands of lubricants may become a nightmare if a manufacturer tries to do it)
Using a special aditive to minimize a design flaw would NEVER be addressed. It would mean acknowledging the flaw...
Just for a starter: I remember the Molykote (molybdenium bissulfide if I recalls correctly) revolution back 40 years. It was not a detergent, an atioxidant etc: it was LUBRICANT. It dealt directly with friction reduction.
No need to say it was very polemic. (despite being widely used in race cars)
I remember it was not accepted in Porshe gearboxes because the synchro rings would sleep and fail to synchronize)
How about this vis-a-vis the current world + auto transmission environment ?
Do we have components that cannot be overlubricated?
