The following bellowis the procedure I copied from the service manual:
AUTOMATIC TRANSMISSION FLUID
ADJUSTMENT
1. BEFORE TRANSMISSION FILL
_ This transmission requires Toyota Genuine ATF WS.
_ It is necessary to refill the transmission with the correct
amount of fluid.
_ The vehicle must remain level while adjusting fluid level.
2. TRANSMISSION PAN FILL
(a) Remove the two bolts and transmission case cover.
(b) Remove the refill plug and overflow plug.
(c) Fill the transmission through the refill hole until fluid begins
to trickle out of the overflow tube.
(d) Reinstall the overflow plug.
3. TRANSMISSION FILL
(a) Fill the transmission with the correct amount of fluid as
listed in the table below.
(b) Reinstall the refill plug to avoid fluid splash.
Performed Repair Fill Amount
Transmission pan and drain plug removal
1.3 liters (1.37 US qts, 1.14 Imp. qts)
Transmission valve body removal 3.9 liters (4.12 US qts, 3.43 Imp. qts)
Torque converter removal 5.3 liters (5.60 US qts, 4.66 Imp. qts)
Entire transmission assembly 5.3 liters (5.60 US qts, 4.66 Imp. qts)
HINT:
If you cannot add the listed amount of fluid, do the following:
(1) Install the refill plug.
(2) Allow the engine to idle with air conditioning OFF.
(3) Move the shift lever through entire gear range to circulate
fluid.
(4) Wait for 30 seconds with the engine idling.
(5) Stop the engine.
(6) Remove the refill plug and add fluid.
(7) Reinstall the refill plug.
4. FLUID CIRCULATION
(a) Allow the engine to idle with the air conditioning OFF.
(b) Move the shift lever through entire gear range to circulate
the fluid.
5. FLUID TEMPERATURE CHECK
NOTICE:
_ On vehicles equipped with air suspension, perform
step (c) if it necessary to jack up the vehicle while the
engine running.
_ The fluid temperature should be less than 30_C (86_F)
before beginning the fluid temperature check.
(a) With hand-held tester
(1) Connect the hand-held tester to the DLC3.
(2) Select the tester menus: OBD/MOBD, ENGINE,
DATA LIST and A/T.
(3) Check A/T OIL TEMP.
(4) Allow the engine to idle until the fluid temperature
reaches 46_C (115_F).
(b) Without hand-held tester (Using D shift indicator)
(1) Connect terminals between CG (4) and TC (13) of
the DLC3 using SST (09843-18040).
(2) Move the shift lever back and forth between N and
D every 1.5 seconds for six seconds.
(3) The D shift indicator on the combination meter
comes on for two seconds. This indicates that the
fluid temperature check mode has been started.
(4) The D shift indicator will come on again when the
fluid temperature reaches 46_C (115_F) and will
blink when it exceeds 56_C (130_F).
(5) Allow the engine to idle unit the fluid temperature
reaches 46_C (115_F).
(c) For vehicles with air suspension (Using D shift indicator)
(1) Connect terminals between CG (4), OPA (11) and
TC (13) of the DLC3 using SST (09843-18040).
Terminal OPA is connected to prevent air suspension
height adjustment from occurring when the vehicle
is lifted off the ground with the engine running.
(2) Move the shift lever back and forth between N and
D at 1.5 seconds interval for six seconds.
(3) The D shift indicator on the combination meter
comes on for two seconds. This indicates that the
fluid temperature check mode has been started.
(4) The D shift indicator comes on again when the fluid
temperature reaches 46_C (115_F) and will blink
when it exceeds 56_C (130_F).
(5) Allow the engine to idle until the fluid temperature
reaches 46_C (115_F).
6. FLUID LEVEL CHECK
NOTICE:
The fluid temperature must be between 46_C (115_F) and
56_C (130_F) to accurately check the fluid level.
(a) Remove the overflow plug with the engine idling.
(b) Check that the fluid comes out of the overflow tube.
_ If fluid does not come out, proceed to step 7
_ If fluid comes out, wait until the over-flow slows to
a trickle and proceed to step 8.
7. TRANSMISSION REFILL
(a) Install the overflow plug.
(b) Stop the engine.
(c) Remove the refill plug.
(d) Add 0.4 liters (0.42 US qts, 0.35 Imp. qts) of fluid.
(e) Allow the engine to idle and wait for 10 seconds.
(f) Proceed to step 6.
8. COMPLETE
(a) Install the overflow plug with a new gasket.
(b) Stop the engine.
(c) Install the refill plug with a new gasket.
(d) Install the transmission case cover with the two bolts.
Torque:
20 Nm (205 kgfcm, 15 ftlbf) for overflow plug
39 Nm (400 kgfcm, 29 ftlbf) for refill plug

Performed a a full transmission flush on my car, it was the first oil change since the car was built, 150,000 miles ago on the transmission.
I talked to one of the head technicians over at the dealership, and it was awesome to know that he owned an LS430. So, he assured me to go ahead with the complete full flush. And that he would do it himself personally.
They charged me $349.99. So far so good/ IN FACT, I feel like the car's shift's are much more smooth and subtle now.
My advice would be to have the dealership take a look at it.

I just bought a Briarwood Pearl 2 owners base model with modern luxury package with 862xx miles, car has consistent services from the dealer, I registered myself as new owner at the "lexus owner" site, this car have no records of servicing the ATF?
Should I change it? the LS drive smooth and shift perfectly (I never drive a car that the auto tranny shift so smooth and quiet), sometime when downshift to a stop, I notice a slight shock, concern?

So after starting the engine for no more than 5 seconds to drained out 1 qt and refill, do you start the engine again to drain it or does it drain after you pump the fluid in.
Thanks

It only will pump out of the transmission cooler line with the engine going. No fluid will come out when you manually pump in new fluid.
Hope this answers your question!

Simple drain and fill -- gets about 3 quarts out. This method can be done regularly to saturate the system with new fluid periodically. If you keep up with this method you'll eventually have basically all clean fluid. This procedure doesn't "shock" the system and introduce 10 quarts of new fluid with the new cleaning additives that go along with new transmission fluid. It's more gradual.
Flush -- a transmission machine exchanges the entire contents of your transmission with new fluid. If you take 10 quarts out, you put ten quarts back in. There is an option to run a cleaner through the transmission when you do this, a lot places won't do this for fear they will damage the transmission depending on mileage of the unit (they might not do this to a higher mileage unit for fear they will dislodge deposits into the valve body or remove friction material).
Removal of pan and replacement of filter and gasket -- This procedure allows you to clean the magnets in the bottom of the pan and replace the filter. This procedure will remove more fluid than a simple drain and fill because when you remove the filter you will release fluid that is trapped behind it (sometimes a quart or more). I don't believe the LS430 has a paper element filter, but rather a metal meshed screen that you can clean out. I'm finding a lot of people don't even consider this option anymore because it's a bit more work...it's messy...and the exchange machines are the norm nowadays (or simple drain and fills). But I like it, I know with my car (LS460), it had a paper/fiberglass design filter that I was glad to replace at 75,000 miles.
Personally I think the simple drain and fills are fine, especially if you do them every 20-30 thousand miles or so. I did that with a Honda Accord I own and it has 278,000 miles on it and it still shifts fine (and those trannies are prone to failure). I believe those drain and fills kept that thing alive.
