Should I shift an automatic transmission into neutral when I stop?

i have posted many newbie questions, this is one of them, do you guys shift to N when comes to stop light or whenever you stop for a short time? i read an article yesterday, and i did it today, i felt like it really eases my brakes, because every time i press brake pedal when light turns yellow, i hear braking sounds on my tire, today, i shifted it to N when i about to stop, there is no noise behind my wheel, so i am wondering shifting to N, would it harm my transmission? which way is better?
2. my another question would be, my car is still under 1000 miles, when i drive on an uphill road, i feel like my car is pushing so hard to climb up, i don't know whether it's my car too new or i just paranoid.

How "hard" is the engine driving up the hill? How steep is the hill? You shouldn't be red-lining every gear up a hill, then you're driving too hard.

I wouldn't shift the transmission into or out of any gear while the vehicle is in motion. That's a recipe for stripping your gears. You can shift once the car comes to a stop; which I've done a couple times. But, again, I wouldn't shift to neutral while the car is rolling.

Automatic transmissions are designed to idle, let them do their thing.

I see an advantage to shifting into N in the hot summer. At Idle, the car wants to move forward because the torque converter is pushing the trans fluid as it should. But holding the car back with the brake makes the fluid "work", which heats it up. By shifting into N, the fluid is not doing any work, therefore staying cooler. Anytime you go up a long hill, the transmission fluid works harder, and heats up. This is why vehicles used for towing trailers and boats need an extra transmission cooler so the life of the trans fluid is not shortened.

I've heard this before (shift into neutral at a stop) but just don't know if it really extends the life of the trans. And in our case with a 100k mile warranty, I just don't worry about it.

Sometimes I do this at long lights. Just make sure you shift back into D before you start revving.

Pointless, and why work the shift linkage in and out? And transmission overheats are so rare in cars, even in the summer wouldn't matter. Trucks have them for loads, and pulling up hills. Pulling a multi-ton up a mountain in 100* does not compare to a sedan in stop and go traffic. High rev the engine once because you forgot to put it back in gear and then what? Illegal in many areas, too, by the way.

I have never ever heard of that - changing in to neutral on an automatic while on a red light.

I leave the transmission in Drive at a light and let the automatic transmission do its thing - reduce the need for me to shift.

If you feel like the car's working hard to get up a hill, check the tachometer to see if the engins is near or below 1,000 rpms. It just may be that the transmission has to downshift to get more power.

Plus leaving a car in neutral is a safety issue. If you need to move out of the way quickly, you don't want to have to shift the car and THEN go. Same with a manual. The car should always be in gear.
