Anybody change ATF after 163K?

As long as you don't take it to a shop to have them hook to any type of power flushing machine you should be fine. The consensus is generally you can change the fluids all at once. You do run the risk of the detergents in the the atf breaking some deposits loose but our transmissions are stouter than most. It could mean a rebuild but we have heard stories both ways. If you are concerned start by replacing just the 3 qts that drain out. Drive then repeat. Then when most of the fluid is new you can decide if you want to drain and refill it completely later. The only problem with this method is the fluid is never completely clean and fresh. Then again, you have not introduced all of the cleaning/detergents into the old system at once either.
I did a fluid exchange with Amsoil fluid at 150k and haven't noticed any ill effects. I believe it was the first trans service it's had.
Changed all the fluid at once by pumping it out of the cooler line and refilling it repeatedly about 3 qts at a time.

I did 4 drain and fills over the course of a week with 159k on it, and it was the first service according to the PO. I replaced the original fluid with M1 synthetic. So far so good but I haven't put many miles on it, just 3 miles each way back and forth from work and then a few errands here and there.
I sure hope I haven't done any harm. The original fluid was pretty clean looking but did have a pretty foul, somewhat burnt smell to it. Mine is a 2000 fwiw.

155,000 original fluid. 1998. Rolling on.
Edit, I added a bottle of Lucas to it....

Mine has 207K miles when I bought it - no history of fluid change. I have some receipts that goes back several years, but not from the beginning. The original fluid looks good, no burnt smell. I have done drain and refill 2x in the past 7K miles with Mobil 1 synthetic with the thinking of introducing fresh fluid slowly, but I plan to flush it out. I dont think the car was used off roading or towing by previous owner, so it has had easy life.
The power steering fluid was in really bad shape. It was black and thick (I should have kept a small sample of fluid for comparison). I have drain and refill the reservoir several time to slowly introduce M1 fluid. It is now dark red, but at least now it feels smooth and liquid. The fluid change color to lighter shade of red when new fluid gets introduced, but then it goes darker red, which seems to support the idea that it is cleaning some deposits. There is a small improvement to the feel of steering, but that could be my imagination. I am also planning to flush it out, most likely in the summer.

Yours uses the WS fluid correct?
I thought they took the dip stick away, the drain plug, fill plug and level plug remained?
I have an 2000 LX470. Has 249,000 on it now. Did first time flush around 247,800. Have had no issues. Still changes sooth and pressure hasn't changed. I'm glad I did it. Bought car with 67,000 on it.

Wow. I think I am ok then. Yours uses the WS right? Was the fluid black? Did yours ever tow or anything?
I will be doing a "power"flush (not the DIY) with WS next week. 160K+ on mine, no clue as to previous history.
After talking to a specialist, I don't see the risk. And if it breaks afterwards, then surely something was already wrong I just accelerated the need for a repair.

I didn't have a record that it had ever been done. I could have been, but couldn't confirm.

What about changing the filter? I assume these trannies have a filter in them?
A filter is not the term I would use. It's a mesh screen. And catches only the biggest crap to prevent further damage to the total system in case of some sort of (catastrophic) failure. This is not an oil or fuel filter type deal that needs changing.
That's it. Sorry for confusion. Mine is a 98 but I remember the 03 I had I could not check it or add Lucas.

Some one waste the $28 already! (Where's the Lexus owners at?)
I already changed mine, so little to be learned.

I believe so.
Update: 255K kilometers. Just had it flushed. 50 miles in seems to work fine. The ATF I had was dark and smelled burned bad. In any case, worth it as PM in my book. Powerflush, so they add a detergent, I cycle the gears a few minutes, and the old fluid + detergent is pushed out and new ATF is flushed in.
The ATF was aftermarket WS that the flush place uses.
Our guess is that ATF was never changed, judging by how the hose was stuck to the radiator.
