The way I look at any of the mechanical components that has fluids, especially a lubricate, it will be better the have new fluid over old fluid that has lost any of it's properties, would you ever not change your engine oil??
I say this over and over, there's no such thing as a lifetime lubricate, all lubricates lose some if not many of the lubricating properties the longer they are used in a friction/heat environment.
That all being said maybe you should take a sample of the transmission fluid and send it off to be tested, if it passes with flying colors, don't change it, if it fails then you will have to make the choice too do it or not.
I'm not sure if I have read of anyone having the transmission fluid tested but I think it's a good idea, it will answer many questions many here have on this subject, if you do this please post the results!!

I am not sure I have ever understood the sealed forever transmission idea. While trans fluid will/can last a long time I think AuSeeker is right here. Speaking as a person with a degree in aerospace engineering, who has spent many years in and around the firearm industry as well, it strikes me that it doesn't take a rocket scientist to know that no fluid is made to last forever.
The simple laws of thermodynamics over a time of, cycles of heat and cold, natural condensation, natural wear and tear, suggest that there's a limit to any lubricity material.
Toyota may be right that flushing systems might not be needed. Perhaps there are a lot of these quick-change places that unnecessarily talk people into flushing systems, and they may in fact do more harm than good. But to suggest that the alternative is never change seems extreme.
I would think the best alternative is draining and refilling. Some do it a few times in a row.
