Got an email regarding the new ES300 from Lexus today, and they describe the
"new" ES trans:

"So the new ES 330 has a new 3.3-liter engine that propels the ES from zero
to 60 in just 7.2 seconds [1]. Coupled with the new five-speed automatic
transmission--which features wider gear ratios and better hydraulic pressure
for better acceleration, gas mileage and smoother, more responsive shifts--"

I didn't realize the trans was a NEW 5-speed. I thought it just had
different programmed shift points.

(I wish they'd offer to replace my '02 trans.....)
