How to shift from D to 2 while driving?

You can just shift it. You might also consider disengaging OD (usually a button).

Thank you very much. Could you please tell me what overdrive for? I am a new driver. Thanks again.

Overdrive is the highest gear. I could tell you why it's called that, but it wouldn't really help you. It should shift down by itself if you push the gas pedal hard enough.

You can do it while driving. Best thing to do is push the throttle far enough so that when the tranny changes down from 3 to 2, rather than the tranny forcing the engine speed to rise, the engine speed is already rising and matches up better with the tranny in 2nd gear, making the downshift smoother.

I've heard these types of questions from people before and I wondered if they were serious.

I just always found it funny that Europeans growing up with manual trannies were as confounded by autos as Americans growing up with autos were with manuals.

TFM?

More simply put, "Just mash on the gas pedal harder. It'll shift itself when it needs to. There's a reason it's called an *automatic* transmission.

Sometimes you want to downshift without flooring it. The car shifts down more soothly and less abruptly.That's one advantage of manual tranny's. The car shifts Only when you want it to.

I didn't mean to floor it when I said, "mash on the pedal harder". Sorry, I'm from Tennessee.

I was actually agreeing with you.

I'll even do it again, I much prefer a manual transmission, but they're getting to be scarce as hen's teeth anymore. :-( I just find it comical when people who've never driven an automatic feel compelled to ask how to shift it.

Unless you're stuck in mud or snow, put in D and leave it alone, it'll do the shifting *automatically*, hence the name.

OK, I see what you're saying. Another aspect to think about, with used cars the automatic tranny fluid is not change as often as it should be. Because of this, the tranny is much less likely to shift down when you mash the pedal, so you ending up having to absolutely floor it to drop down a gear.
