It's normal, partially an emission reason and also to help warm up the fluids particularly of course the ATF fluid.
Believe me, it's one of the few irritations I have with this fine vehicle along with the turning radius.

it is normal, but RX300s have transmission problems in general. does it make a winning noise in the morning? if it does go and have it checked as soon as possable. you can do more damage if u keep driving it..

Normal and my understanding is the whine is normal too because things are spinning pretty fast in 1st gear before it finally allows the shift to 2nd (only does it when it starts getting really cold). Mine has been whining since i got it when temps get down in the 20's. Goes away after a min or two of driving. Have done a few drain and refills, 195k on it but still shifts nice.

I dont hear a whining noise. I had problems with it goin into od and noticed i had an exhaust leak so i took it to the muffler shop and the front o2 sensor had broke loose so they welded it back on and now theres no cel and shifts fine into overdrive. Im happy about that because they told me it was most likely knock sensor but i havnt had any problems since they welded the o2 sensor on. It was getting to be a pain not goin into overdrive i had to keep shuting the car off and restarting it that why they though it was knock sensor.Anyway im one happy gal a 30 dollar fix. Im glad to know the cold shift is normal and not another problem. It wont hurt to drive it under 3000 rpm until it shifts is it?

Yeah, it's annoying, and odd, but "normal". Higher revs aid in warming the catalytic converter after a cold start, so you'll notice it more in the winter.
I know it's better for the environment, but it annoys me, anyway.
Unless you live someplace truly cold, it shouldn't do this for very long...maybe five minutes of drive time.
