Correct.

And so far no correlation between not changing ATF and shorter transmission life has been "proven" either.

When it comes to maintenance actions, very few have actually been "proven." "Proof" is often hard to come by. I know someone who did their very first oil change on a Toyota Corolla at 25,000, which had the factory fill of non-synthetic oil, 25 years ago. Their engine was still going strong at 100,000 miles when they sold it. But that's not proof and I still think I'll change my oil more often than that and pay for synthetic oil.

So again, it's a judgment call, and people have to make it on the information they feel is important and/or the "experts" they trust.

I myself believe in changing the AFT; however, I can see the argument for not changing it, and I am open to the distinct possibility than I am wrong.

If anyone ever comes-up with some hard data that is statistically significant, I'll be very interested.
