'09 Paddle shifter question

They control the highest gear you will allow the automatic transmission to use.
If you happen to restrict it to a range lower than what it's in when you hit the paddle then it'll be forced to shift to the highest allowable gear though, albeit indirectly.
And yes on 09s they work in D too.

i love this option and wish my '08 had it too...

The paddle shifters don't actually shift.
They control the highest gear you will allow the automatic transmission to use.

you wont harm the tranny... or else lexus engineer wouldnt give you that option.. braking at high speed probably does more harm to the engine than shifting to 5th gear in D mode at 80mph.

when you paddle the gear back to 6th, independent of the speed you are at, it resumes normal full auto operation

Again- the car -always- shifts on its own. You never directly shift it.
The only thing you can do is limit the range of gears its allowed to automatically shift between.
While you're not going to really hurt anything with the occasional engine braking it's not a good way to slow the car down on a regular basis, since it does put a bit more wear on the transmission each time you do it. Brakes are a lot cheaper to replace than transmissions in the long run.

Well, that's not totally true... there's some situations where limiting gear range is useful... driving down out of the mountains for example where it'll keep your brakes from overheating... In theory I could probably conceive of a couple of odd highway passing scenarios where moving it over to S (to drop it from 6 to 4) right before you're gonna gas it might be useful...
But overall it's not good for a whole lot besides fooling people who don't understand it into thinking they've got some kinda SMG type system when they really don't

More complex, thus costly, to develop a "real" safe and reliable manual shifting option for an auto like that... especially for when the car was originally developed (this method is totally BS electronic trickery versus doing anything mechanical.
keep in mind the 2IS was first shown in early 2005, so the "technology" behind much of the car is 5 years old at this point.
The IS-F can, on the other hand, behaves how you'd want the ISx50 to- shifts on demand, holds gears, etc...
I'm sure the next gen IS will have this on all models... but if they were ever gonna add it to the 2IS then the 09 revision would've been the time and no dice.
