I've done it in a Silvia auto.
It's ace and good fun, but you'll you'll probably lose about a second versus an equivalent manual car.
Hold the brake on the line, wait in drive, lights change, nail it. Job done.
Alternatively.
"N" on line, raise revs to about 4000, when lights change bang it into 1st, this get a bit of wheelspin, but the torque-converter kicks in and it can bog down abit.
I got better times overall with the 2nd option, but better reaction times with the first. Try both and see what suits.
