You are what makes forums still great! Absolute goldmine of info from you in this thread.

Just drained and refilled my atf. Came out exactly 2 qt. So I decided to try let the car runs until it reaches 104f. It took almost 6-7 minutes. Is that normal? about .25qt came out. Is that also normal? Any feedback would be great.

That sounds correct for your car. The total fill amount does appear to vary among those who post. It may be how level the car is, or manufacturing tolerances, such as the original fill amount, or how each person measures the amount drained and replaced.
It does take time to warm up the transmission when just idling and not driving around.
If you had overflow at 104 and are comfortable with your work, then assume all is good and take it for a test drive.

It's not clear - does the RX 3 gen has a transmission filter? I can't see it on diagrams.

The drawing you linked is for the transmission case. The filter is not shown in that drawing. It is shown in the drawing for the valve body and oil strainer which is another name for the filter.

It is called either the filter or the strainer assembly for the valve body by Lexus. You need to enter your VIN to be sure you get the correct filter. This is the correct page from the link you provided https://www.japan-parts.eu/lexus/eu/...l-strainer-atm

The fillter is inside the pan. This link is for changing it on an ES350 but it is almost exactly the same for the RX. https://www.clublexus.com/forums/es-...placement.html

just had my fluids drained and refilled, but the mec just did a measure of fluid out (1,9L) and added 2 bottles (2L). ES350 2013 has a total of 6.5 L i believe.

how precise should the fluid in and out be? would 0.1 L difference be a cause for concern?

Don't worry about it but try to stick to the exact amount you drain next time. Best way in my opinion is to check the level of oil at the operating temperature.

I don't think .1L is going to make a difference. The previous owner of our RX did his own drain/fill and when I did one 10K later I got 3.7 qt out of the trans. From what I've been reading most people get 1.6 to 2 qt out. I put 3qt back in and will soon do another drain/fill to see what I get out. Trans has been running great, no issues.

Maybe in your case it would be worth it to go through the fluid level check procedure? I would do it if an unexpected amount of fluid came out of my transmission.

Has anyone located the fill and drain plugs on the F Sport? I will get down there and find it myself if i have to but would love the assistance ahead of time if someone has the answer. Thank you in advance for the assistance.

At the bottom, next to the frame where the pan/drain plug should be, there is shiny transmission body and some funny looking bolts. Does anyone have a 2015 f sport that looks like mine and has changed transmission oil? Can you please post some pics and hints?

I just picked up 5 quarts of ATF ws from Lexus for my 2010 RX 450h. From what I've read if you only drain out 2 quarts max then why would the parts person recommend me that much?
