I just bought the 2012 Honda accord coup 2.4l auto.EX.My question is can i use the D3 gear to slow down the car and come to a full stop instead of using the break?I seem to be using my brakes a lot to slow down and come to a full stop.Your input is highly appreciated.

Doing so not only wouldn't work, but would be extremely unsafe. While compression stopping (downshifting and using the resulting "engine braking" to slow down) is possible with manual transmissions (and, to a lesser extent, with automatics), it can not slow a car to a complete stop. You need to use your brakes. The purposes of "D3" are simply to lock out the overdrive gears to keep the engine in its powerband when climbing hills and to keep vehicle speed consistent on downhills. That said, because Honda automatic transmissions have Grade Logic Control, which holds lower gears when an incline is sensed, using D3 is generally unnecessary in all but extreme situations.

I used D3 on a daily basis when on my highway commute (not interstate). When a light changes ahead and you're going 50 mph, D3 never hurt anything, it just aided in stopping. I used the brakes too of course.
I put 235k miles on my Accord and it was still going strong until an 18-wheeler clobbered me. Never a transmission hiccup over 15 years.
Use D3, but do so intelligently. If you're revving your engine to over 3k RPM when you downshift it, you're likely putting more wear on your tranny than your brakes.
