I stop the car at the stop sign then drive off, but a heavy on the gas until the car is doing about 3000 rpm in 3rd at which time I let of the gas (about 10 seconds. The car then rolls to a stop at the next stop sign. Then I head out on the highway and no matter how hard I floor it the 3-4 shift is smooth without the flare.
If I just drive normal (without punching the throttle) from the first stop sign taking it easy, then when I head out on to the highway I always get the 3-4 flare (higher rpm flare with heavier acceleration).
I know we shouldn't have to drive a specific way to avoid the flare, but the fact it is possible indicate, to me, a programming error in the tranny logic controller.

It occured to me today that rather than fix the problem, I could try to convince the dealer to install remote start so I could fire the car up a few minutes before leaving in the morning.

OK, that makes perfect sense now... I could probably do the same thing considering my typical starting commute, I'll try it.

That's it, the solution, TSIB issued for remote start addition under warranty or we can all get our cars up to point of shift but back off for ten seconds, then apply gas again.

onsknht,
You almost have it. Think ENGINE WARMER. Using a variety of methods we have been pre-warming our ES350 engines for a week now. My neighbor and I experience the QUIET of a Lexus morning startup now. As hard as we try, there are NO rpm spikes with a pre-warmed ES350 engine here.
We also have opinions on what the rpm spike really is and one of its causes, But, expressing that would just lead to more hyperbole from certain posters on this forum.
I can now understand these anomolies starting in the colder climates.

I have issues with Lexus, but messing this one up is not one of them, it is the reason they instruct that the car be COLD when started and not a slightly or totally warmed up car, whether the car is located in a colder climate area or not.
It is not news to Lexus that this happens from when the car is cold started and driven or that it does not as a rule when a car is warmed up, that seems to have been overlooked that they deserve credit for that observation or their detailed instructions to duplicate would not include the cold requirement. Allow anything time, even an impeded valve restricting fluid flow and it will allow more fluid present than otherwise would be if not waiting before starting out in the car. E.G., if it is only getting half the amount of fluid at 1 minute after start and you "think warm" and allow it another minute, it has the required amount it needs not to slip, that doesn't make it any less a mechanical problem though, just a time consuming way around a correctable mechanical problem.
