When did you change the transmission fluid last time?

I would call the dealer and explain the issue. Do not forget to mention that the dealer has recently replaced the fluid to address the issue.

I'd have them remove the transmission pan, clean the pan magnets, and replace the transmission filter. Simply draining and filling doesn't remove all the gunk. If your over 150k miles the magnets are likely saturated, unable to collect any more debris until the pan is dropped and cleaned. After that if the issue comes back I'd have a shop flush it.
Your tranny has the same magnets as this

Backflushing can restore trans operation.

I tried drain and fill then the backflush. Noticeable improvement.
Steve at luxury motorcars mentioned that at 100k plus miles some trans start to shift erratically. Backflush fixes almost all of them. Btw 60k out of the USA is the trans fluid change interval.
no pontification please. You only know what you know. Not everything. The backflush cured my Toyota solar convertibles erratic shifting at 150k miles also. Drain and fill helped but the backflush fixed it.
‘Like I said the Lexus dealer here in south Orange County, ca. does backflushes for many years without incident. Maybe you should call them and tell them and Steve that they are wrong?

my Lexus dealer(south county lexus), owned by warren buffet offers and does perform backflushes. Luxury motorcars in Monrovia,ca, the luxlink builder for remote sc430 operation also performs them. No issues.

What you should do it change the filter so the pump can actually flow fluid properly then backflush it if you still want to risk damage vs just draining and filling.

Maybe I haven't been paying attention and I haven't searched for it either but I can't recall anybody posting to say the had a flush performed and it took out the trans.
I have read of people that have fairly major problems that ended up in trans replacements but those tranny's were probably too far gone anyway.
The term backflush is wrong also because the pump is controlling the flow of oil and the machine only adds approximately what is pumped out, nothing is going backwards.
I've done lots of flushes if you want to call them that, they are just fluid changes...with a machine on pre WS sealed transmissions and this was without a filter/screen change with zero problems.
I think it's the filling procedure where things go south, with a "flush machine" hot or warm fluid id taken out and room temp fluid goes in and that has a different volume. If you think flat rate people are going to spend much time on getting the level just right you are mistaken.

Get your dealer to commit that they will replace your transmission at no charge if it fails after the flush. If they are good with that, go for it,

Do you think that the flush actually caused the failures for those people or is it because people are just driving the cars for 100k + miles with no service and had existing problems that were going to end up in failure whatever they did?
Some people state they drive those miles and more problem free without a service, I believe that fluid has to be changed along with the filter at regular intervals.
That filter looks like a felt blanket.

my local Berkshire Hathaway owned lexus dealer has done thousands. I think they do not recommend it at ultra high miles. 150k plus?
