Some dealers do not have the machine to do the exchange nor the tech proficient in its use!
It's interesting that on that link at he bottom of the page on the right with an ATF machine picture it says....Aisin recommends the use of ATF exchange machines.

I found one lexus dealer that will do the ATF exchange, along with number of Toyota dealers. I also had a lot more intelligent conversation about the procedure and need to do ATF drain/flush with this dealer. They explained how they do it, and that it’s safe. The lexus dealer that does NOT do ATF flushes sounded like a broken record quoting the manual without any explanation, which just lowered his credibility for me.
people don’t realize, but so called owner manual, also never mentions that you need to change your power steering fluid, but everyone knows that if you plan to keep your car to 200k miles, it would be wise to replace power steering fluid every 60-70k miles. I even had this recommended by the dealer that does not do ATF flushes. Are they using owner manual whenever it suits them? Maybe they don’t own transmission flush machine (which is expensive), and all of a sudden they like what the manual says.... I don’t know, we can only guess what are the reasons for dealers to reject ATF exchange. Some are just ignorant and playing safe, you can always cover you *** by saying “look, it’s in the book!!”
but the facts are pretty simple, fluid gets nasty with time and miles, and you have metal shavings in the pan. Look at the pictures of oil pan with nasty fluid and metal dust that never was changed at 150k miles. All these things are not good for your tranny and odds of it going bad will go up as you are in 200k mile club. If you plan to keep your car till 200k miles, one time flush sounds like a good investment to me.
Go on YouTube, watch videos of mechanics about sealed transmissions, see what they say if you are not convinced. And please, stop bringing up toyota engineers know best, turns out it’s not even transmission that toyota makes.

This is excellent. People keep saying "toyota engineers are smart, and they said do not change it blah blah..."
However, transmission is NOT designed by toyota, it might be designed FOR Toyota by Aisin. And AISIN itself is calling BS on "sealed for life".
I have a feeling that Lexus dealers that do not do it, are simply going by the book. Its easier for them this way. Any problem with transmission, they will say "we just did what the book said, not our fault". I can see that this makes things easier for them,

Also people forget the the owner's manual is a compromise and written mainly by marketing people. If one wants to get close to real maintenance schedule one must read the Severe Maintenance one, but the problem is that manufacturers know that the average original owner will not keep a vehicle beyond 5 years and if leased 3 yrs on average so all theycare about is the warranty period. Once out of warranty you're SOL, so let common sense and some knowledge be your guide.

I was making a point that not everything in your owner manual is accurate. Its not a bible.

Not only do I think you should do a flush (since you will be doing it at a real Toyota or Lexus dealer; I wouldn't trust that to too many places, the equipment used is very specific), I would do a flush with a better ATF such as Amsoil Signature synthetic. My car shifts much better with it and I trust it much more than Toyota brand oil which I hear is *not* synthetic.
If you will drain the pan only (I think thats only about 1/3 of the oil in the transmission system) then you should do that every 30k miles which will be more costly if someone else is doing it.
Again I would not trust the flush to just anybody, you need special equipment and knowledge.

I spoke to one that owns a Highlander. He said he flushes the transmission oil on his own car every 60k miles.
I would also drop the pan and change the paper filter and clean the magnets of metallic debris every 110-140k miles (just my guess). I heard a guy did it at 100k miles and he had lots of debris on the magnets.

Servicing sealed transmission is not a simple task and must be done properly, or damage can be done.
Overfilling/underfilling or fluid contamination can happen.
I would only use Toyota ATF WS fluid.
unless you know someone, I would only take it to lexus/toyota dealer.

i used to get my tranmission fluid services every 50-60k well i feel it was stupid to do so because by 150k i started having some issues by 190k transmission had to be repalced
i say flush it only if somehting is wrong with it and you are trying to see if you can revive a dying dog. otherwise don't mess with it.
Now im not sure how this goes for the ES300h Model someone once on here i think said it only holds a few qrts and it's simple and easy to drain a few quarts and fill the fluid with the exact same amount but not to even think about it until 150k i think i dont remember

Is it possible the failure had nothing to do with transmission fluid change?
if you wait to change your transmission fluid when it’s been there for too long, that’s when you are asking for trouble.

I did it twice, at 60K and 110K miles.
Both oils were burned.

Who/where it was flushed
Method of flushing
What fluid was used
The experience of the technician
To make such a broad statement doesn't help w/o details.
