Overdrive is better for gas mileage. Driving in D will only let you go to 3rd gear. It makes the car more responsive in city driving as you wont have to shift down out of OD to accelerate.

Overdrive just makes the car shift to the highest appropriate gear to keep the rpms down and reduce fuel consumption. It's better fuel mileage and less wear an tear on the engine since its revving t a lower speed during everyday driving. Driving in D is acceptable too though. As stated it just makes the car more responsive.

camaro shift plates go (D) D 2 1
firebirds shift plates go D 3 2 1

putting it in (D) is the best thing for the car.

From the Manual:

"Here are some times when you might use Drive instead of Overdrive:
-When driving on a hilly, winding road.
-When towing a trailer, so there is less shifting between gears
-When going down a steep hill."

Overdrive is for normal driving. Use it. The transmission won't use overdrive until after it needs to use 4th anyway.

Really unless your drag racing in a built auto theres no reason to take it out of overdrive unless towing or going down a hill. Just dont be the cool kid whos slamming his auto through the gears all the time, best way to burn up the transmission

It won't go into overdrive if the throttle is greater than like 35% so even if you're drag racing there isn't much point to put it in D instead of (D).

I meant like a manual valved auto. And mine shifts into OD after its out of room to run in drive no matter what the throttles at it just changes my shift points.
