Man i am crossing my fingers on this one - I had a 99 accord v6 go south on me because of this tranny crap. Sometimes it holds revs high like it won't upshift (usually bounces around 3K rpm). Not too worried, just leaving it in full auto and hammering it once in a while.

 

I had a 07 IS250 awd for a loaner car with 7K miles on it and I felt the car shifted alot harder than my 01 gs430.

 

You have to change it at 60k and every 30k after that or you will have poor performance, rough shifting and a dead transmission. When you change the fluid make sure you change the filter. If you don't believe me look at what color the fluid is at 80k... It's almost black with the magnets full of metal.
