320k miles with no problems, and you wonder if its any good? Sounds like its working.
I had a problem with the fluid turning brown, thats with the trans under 20k miles on my Civic, did some reading, and everyone said that, using anything other than Z1 fluid would cause the auto trans to shift funny.
Not wanting to take a chance, I followed the advice people on this board gave, and purchased a case of Z1 for $80, and did drain and fills every 10k, the brown fluid has not returned, guess its worn in now.
I would say its good fluid just pricey.
