The tranny's fluid has to be checked for leakages, but not changed. It's completely sealed and doesn't require change.
This issue has been discussed here before. You may use the search engine here and have a look at a Lexus document that talks about this issue in detail.

I have just changed the transmission filter and fluid.
it is NOT "completely" sealed, check my other thread for the gruesome images of metal shavings on a 92,000miles LS460 transmission pan.

Nice bucket of coffee ya got there! LOL.
I had my dealer change out my fluid for 148 bucks taxes in. With the requirement of Techstream to do this job and all, I figured I'd let them do it.

that is a very good deal!
my local dealer wants $380 for a drain and refill, which does nothing considering there is still 7 quarts of dirty filthy fluid with lots of metal shavings in there. And that doesn't include changing out the who knows how clogged filter, (probably all by-pass now).
does your $148 deal include changing of the filter? and also hooking it up to a machine to replace all 10 quarts of fluid inside the torque converter and everywhere else?
It actually does not require tech stream to do this job, there is a shifting sequence to put the transmission in fluid temperature detection mode.

I changed mine out at 73k miles, the fluid was dark...which made me think I had to drop the pan and change the filter (which I did), but in all honesty everything was very good in there (magnets weren't covered very much).
At the dealer the parts guy told me this fluid changes it's color very fast - to dark - I'm not sure if I believe him because he thought the car had a metal strainer for a filter (when it actually has a replaceable paper filter). The guy told me "all lexus cars have the strainer". I told him I had the pan off and it definitely was a paper filter, which I got at a local parts store for $50 bucks, including the new gasket.
One thing is certain, I would not let this fluid go past 100k. I read somewhere on the internet that in the Middle East they change the tranny fluid on these cars very 50k, probably due to the heat. And I will say this, I have never seen tranny fluid get that dark before as it had on my car with only 72k on it. There is a thread on this site where a guy sent his fluid to black stone laboratories to have it tested at 100k...the fluid increased in viscosity, it had high levels of aluminum and other metals in it (probably due to planetary gear set wear, clutch material, etc). All in all the tests weren't all that bad...acidic levels were relatively low, but personally I'd want to change it just to gradually get some of those contaminants out. I understand that abrasives aren't necessarily a bad thing to clutch packs, but excessively high levels aren't good for a valve body either, especially if they block a solenoid.
So I did the tranny fluid change, with filter and new gasket. I got every drop of fluid out - more so by accident - because I initially did a drain and refill...changed my mind and decided to drop the pan a week later. Then a week latter I was concerned I didn't fill it properly and ended up changing even more fluid. I will be doing 30k drain and refills from here on out. I will never drop that pan again. Nor will I ever put myself through the fluid level check procedure (heating the fluid up, jumping the connectors at the DLC, shifting it 6 times through the gears, pulling the over flow plug, get the fluid to lightly stream out). I will simply drain it, measure what I took out and fill the same amount back in through a pump.
