Don't procrastinate on your ATF changes!

Also, I'massuming it would be necessary to put the car back down before refilling the tranny fluid - so as to get a proper reading from the dip-stick. Is this correct?
Thanks.
Before I do this again I will take a sample & get a analysis on it. Less then $20 & I will find out just what is going on in there & if it needs another flush out.

I purchase their kits from Amsoil's web page.
If u want to purchase products from Amsoil at low prices become a "Preferred Customer" Click on their web page in the center of the page u will see where to click on. Then use my #66180 & for a small fee you can order anything a big discounts. I think it costs u about $20 for a 6 month period & then if u want to continue you can become a yearly member. Anyway I hope I answered your question.
So we end up looking for statments as "exuivalent or exceed specs" or go by hearsay ... this is the identical product but labelled differently or simply buy it from Toyota/Lexus.
My view has been: Major cost is in labor and inconvinience. So go buy it from Lexus or Toyota.

One thing I learnt in life has been, tests are fine but always answer this question before you opt for the test.
"Based on the outcome, what different steps are you willing to take?"
In other words if you are not willing to do anything different to change (or possibly have an influence on future outcome) then it is not worth the time/energy/money to opt for the test.
So if you have a plan (more frequent change /sell your vehicle/ buy extended warranty etc) then go for it.

1) It is against the Federal law for automaker to condition warranty on owners buying OEM branded parts for services. If OEM branded part or service is a condition for warranty, such part or service must be provided for free.
In short, it is illegal for Lexus to deny warranty service simply because one uses Mobil or Amsoil spec complying after market fluid.
2) Opportunity cost of not using with a superior fluid. Aisin Warner spec complying ATF that is made with real synthetic oil can resist oxidation better. RX's tranny is notorious of generating heat that requires ATF change ~15K-30K, are you satisfied with going with a inferior ATF but stick with a tranny repair bill after powertrain warranty expires?
3)Waster of $. What is the cost of ATF per mile? What is cost of time and gas for more frequent ATF changes? It is naive to look at the sticker price of ATF per quart but refuse to even think how many miles does it give you? I will take $7.5 per quart for an ATF that gives me 60K miles over the $5 ATF that only gives me 30K.
4) Creating unnecessary chemical waste. Ever think of where ATF go if one sticks with 15K schedule? Even if recycled only 2 out of 5 quarts can be reused. Left un-recycled, you just dumped 5 quarts of highly friction modified petroleum oil into the environment.

See this official TSB from Mazda that requires owners to use either Mobil 3309, Toyota T-IV, or specified Ford/GM/Volve ATF.

It is clear at least these ATF are interchangeable because they are all Aisin Warner transmision spec complying. Remember if they are not, Mazda has the liability of providing tranny replacement.
There is no surprise why automakers want to promote/imply OEM branded ATF as the sole qualifying fluid for warranty. But I am surprised most owners actually believe automakers have such right.
Here is what the federal law say. Exact quote from

Let me clarify ...
If you are looking for Toyota T IV buy it from Lexus/Toyota.
Specs call for Toyota T-IV so you need to buy equivalent or better. [Dexron II & III etc are not]
