factory fill "lifetime" Toyota WS with 43k miles on it. I did a full flush with Amsoil ATF which has done very well for me in other cars.

 
Thanks for sharing. Your wear numbers aside, I can never garner much from an ATF UOA.. but ATF isn't used in a combustion type of scenario so I guess it doesn't need a lot.
 
Thank you, i just changed the factory fill in my Toyota with ws at about same mileage. Was curious how well it might have held up
 
I changed what I assumed was the original WS in my Prius at slightly higher mileage than that. It came out inky black, but I couldn't find any ferrous particles by stirring it with a small magnet. That's not directly comparable, because there are no brakes, clutches, synchronizers, or any other friction devices in this transmission.
