Default Procedure!

When you drag with an auto do you just sit it in drive and go? :S

Or should you shift L > 2 > D?

If you shift it yourself can you shift without pulling your foot off the accelerator? or should I do it as a manual?

Should I have overdrive on/off?

On sports TEM with PWR on obviously?

I might be going to Perth on the summer holidays so I might try and get into a drag event over your end of the country.

But I have no clue what to do.

I don't intend on street dragging, especially since my last threat but i would like to know what to do and perhaps practice it on some private roads at my mates country home( 2 WEEKS OFF SCHOOL WOOOOOHOOOO!!)

i shift from l 2 d my self, there is no need to lift off the accelerator.
d is 3rd overdrive is basicly 4th gear.
with it in "d" it will shift gear when it wants to if you shift gears your self you can get it to hold gears longer.
the pwr button only makes a difference when the auto is in drive, it changes the auto shift points.

That's what i thought.

Does shifting like that damage the trans?

I'm a noob at autos, barely driven any auto cars but here's my input..

Shifting it manually is usually faster cause in most cars you can squeeze a bit more RPM out of each gear than what the auto computer changes at. Shift while leaving foot on accelerator.

To launch quickly you need to load the car up onto the stall converter by holding the brakes on with your left foot and holding accelerator until you feel the car starting to slip forwards past the power of the brakes. Then you just release the brakes to takeoff but it'll probably just do a burnout at first.. you've got to experiment and find the right amount of revs that let you take off with enough traction not much wheelspin. However I've got a feeling stalling it up too much will heat the stall converter which shouldn't damage it much but it is wear and tear more than usual.

Anyone feel free to correct me if im wrong

no shifting like that will not cause damage.
the biggest problems with autos is heat
when you go to mates place practise your shifts to find the timing so you can shifts as late as possible with out hitting the rev limter

I've got no clue lol. His dad is mates with my dad and they only just bought the property.

I think it's near the SA/NSW Border but i'm not 100% sure.

Dad's at work right now so i can't find out either.

Cant be stuffed reading all the post but this is what some of my mate have done. SR20T auto.

Keep it in neutral give it a bit of rev (3-4000rpm) and when you ready, drop the the gear to what ever the last number/letter is and off you go then slowly go back to "D" drive.

works a treat but dont think it will to the auto box LOL.

I ruined my sr20det auto that way, after snapping a 12" fence pole with my front bumper (no damage ftw!)
