I did not see any mention or reference that the transmission has any ability whatsoever to 'learn' or to 'relearn' anything, based on previous driving characteristics or not, at any time - short-term or long-term. Obviously the transmission has very sophisticated controls inherently built into the transmission and the ECU which controls its performance and operation based on the driver's input. But, I do not believe the transmission's future operation or performance can change or is meant to change by driver influence relevant to how the car has previously been driven. In other words, I do not think the transmission or its ECU has the ability to learn or relearn anything from how the driver drives the car or how the driver makes the transmission shift.

I presume you specifically mean automatic transmissions, not 'cars' in general (as-in a car's ECU) since the discussion was pertaining to whether Lexus' transmissions have learning capabilities. To my knowledge Toyota/Lexus automatic transmissions do not have learning capabilities... Wonderful for Porsche with their Tiptronic transmission...

Pretty much every modern transmission has some "learning" capability to adapt the car's shifting to how its driven; it isn't just valve-bodies anymore.
and this isn't even touching how the ECU and TCU interact, and what learning capability is built in between those two devices, let alone all the rest of the computers built in the car.

I purchased his tune for my tacoma, and the difference in night and day. He has deleted all the different maps so it drives much more consistently.

Here is a good write up on the "learning" in the Tacoma (similar logic that toyota is using in all their new vehicles)

I did not see any mention or reference that this 3rd Gen Tacoma transmission has any ability to 'learn' or to 'relearn' anything based on driving/shifting characteristics, which was my assertion concerning the transmission in the GS 350.

Today i discovered follow me home lights. They work little bit different than in german cars.
1) Turn OFF engine
2) bull high beam switch one time
3) Close doors and the ligts will stay on 30s by default (that can be change 30, 60 to 90s)
I also changed these

So many features, but the "full throttle mode" is the winner for me. Without exception, each start up begins with pedal press to the floor and then ignition 
I can't see driving without it. Thanks for the suggestions early on in this thread.

Full throttle mode is basically a small tactile detent in the gas pedal. To access it you would need to step on the gas pedal all the way to the floor. And right when you think it has reached its full travel you have to apply more pressure and go past that detent. You will feel the detent.
It is also known as the kickdown switch. Check this thread for many references. Enjoy safe driving.

Yes, I’m curious too, why?

That is what was required years ago with carburetors. When cold starting the engine you pressed the gas pedal all the way to the floor to squirt some fuel into the intake manifold, and also increase the idle rpm speed and 'set' the choke so the engine would run rich until it warmed up a little. Otherwise, the engine would conk-out or stumble and run rough. Fuel injection changed all that...
