I think eveyone is still forgetting about the filter. New fluid is better, but even if the old fluid is still good enough at high mileages, the original filter will not be doing any good after 60-100k miles. I suspect that it will be in full bypass mode by that time.
Old fluid or new fluid, without a properly functioning filter, unmitigated wear metals and clutch material is circulating through the transmission causing accelerated wear leading to failure.

I was referring to many documented failures, swissfranks being only one of them. While some are snap rings, others are temperature sensors, wiring, actuators, or broken metal pieces that are static, ie not dependent on lubrication. What these failures have in common is a lack of connection to fluid condition. One could make a case that the various o-ring failures are related to the fluid condition, but it would be only a guess.
I hear your point on the filter, but do you have data that suggests that clogged filters are causing transmission failures? I equate fluid failures with burnt clutch plates, and clogged filters with low fluid pressure, again often appearing along with burnt clutches and evidence of overheating. The overheating failures we have seen documented have been linked to mechanical failures that resulted in overheating, ie the burnt components were a result, and not a root cause.
