shifting quirks..

i've had my is300 for about 2 weeks now.. sometimes when i'm accelerating from a stop i notice that in between gears the car seems to lose all rpms for a moment then shifts into the next gear at which time the rpms jump back up and the car lurches forward.. sometimes the pause is as much as 5-6 seconds.. its quite odd.. only does it a couple of times a week.. is this a problem with my car or have others experienced this as well?

Sometimes when you are in between releasing the gas and pressing the gas, there is a slight hesitation...otherwise, everything is fast.

OR I maybe a bit too crucial...

this car is perfect.
I think thats pretty much the nature of the beast.
I have a similar problem - not for 5/6 secs - but for a second. It is happens a couple of times a day. I will have the dealer look at it at 1K. Annoying, but hopefully correctable.

I have the same problem sometimes that I think is what your describing. It really only happens when I come to a stop fairly slowly and then try and take off much faster...

The transmission is going through it's learned memory process. Give it about 2,000 miles and I'll bet the shifting will change as it learns. Mine did the same thing.
I got the same problem too...that hesitation in between shifting from 2nd to 3rd. It's a split second but when it shifts the car lurches forward like crazy.

To get rid of this, I turn on the ECT PWR button. I haven't gotten this problem ever with this on. To test, I turned the button "off" and the next day the hesitation problem came back. Turning it back on and it hasn't come back. Extremely weird and disconcerting considering this is a Lexus and the transmission is supposed to one of the selling points of owning a Lexus (i.e., the smoothness of its shifts).

P.S. I have about 9300 miles on the car.
