I dunno if this helps but I tried holding the brake w/left foot and rev the car up with the gas...
I went to 3k and launched, I definitly got a mutch beter launch than a stand still and flooring it, the only thing that bothers me is that I might be wastin my breaks. can anyone shed some light on this? It would be nice to launch like this in an auto, but not if its gonna kill my breaks...
I was thinkin about the e-brake, but wouldnt that be usless? it only holds the back tires

^^^I did that and put it up to 3k and like you said it made a big difference.
..but then the second time I tried doing it, it made this sound like metal twisting. So I stopped doing it. I read that it'll mess up your CV joints(not just your brake pads) which are costly to fix.

manual shifting wouldn't bother the brakes at all (far as i know)...techincially you would think that it would help. by brakin in a different gear or downshifting the braking would be less harsh than it would be in overdrive. that is with normal driving
from the launch it wouldnt be any worse on the car than a manual...the only downfall of shiftin an auto is the wear and tear on the drive train and stuff from there not being an actual clutch to help shift it through the gears

What about from a stop, start in L and shift your way up to drive? Ive been wanting to try it, just to nervous to mess up my trans. And I never downshift or N drop.
Can someone tell me if 3rd has overdrive on it?
Anyone else have some insight on the auto?

well.... my buddy ALWAYS shifts while driving. no matter where we go, he's doing it. i dont think its such a good idea, but he makes it seem like it adds 20hp or something lol. i'll keep everyone posted and see how the tranny holds up.

it is way ok to shift from start from 1 to 2 to 3 to overdrive
it even kinda ok to down shift to aslong as you know at what rpm and at what speed the gear is, it should help actually with brake wear....
the only thing you cant do is throw it in reverse at hig speeds...
the only thing about shifting manually in an auto is the fact that there is no clutch to ease the gear changes like with a manual....it should not cause any major problems, however there is the wear and tear on the coornatiding componants to worry about from the constant shifting. the only thing leaving the car in D is that is just shifts for you and at a very safe rpm with the least amount of wear and tear and pressure on the car.
droppin at 3k rpm shouldn't do do much damage to anything either. the sound is just you holding the brakes while you mash the gas causin the lurkin feelin and that sound....
granted if you shift all the time in an auto it is not good (my dad just used to call it cleaning out the system lol) it is not recomended and not nessicarly good for the car but hothing really is at anything you do even regular driving causes wear and tear over time. i never had a problem with shiftin in my auto and manged to even beat a manual OZ on the start by shifting. i used it a lot off the line and for autoxing i would start in 1st and leave it in 2nd or 3rd since my speed never got high enough to really need more

I have to kill the auto shifting myth. If your car isn't manual or some sort of tiptronic tranny, don't bother doing it. Trashing an auto tranny will burn a sizable hole about the size of a car down payment . . . trashing a manual, get a new clutch, unless busted up the synchros or grinded teeth (ie DSM or WRX for the latter).
The 2g NT eclipse guys loved to promote manually shifting auto or leaving it in 3rd gear for better acceleration (ya, up to 40 mph). Unfortunately, they haven't seen trashed trannies from S-10 w/ 4 bangers when HS kids think it's faster to column shift the sucker. There are tons of them in the used car lot before they are auctioned to salvage yards.
N-drops are the #1 killers of auto tranny. Column shifting will kill an auto tranny within 3 years or so. Then again, how many people change their auto tranny fluid? This kills it too. It's like changing your regular oil on a 10-12K cycle, unless having a chevette (seen this done once. Of course, the chevette was dead soon afterwards).
The ATF has a certain amount of heat resistance. Once its tolerance is near the end of its cycle, the tranny can be ravaged by heat/stress from manually shifting the auto tranny. If you have a shift kit, shift away like those classic big block boys w/ 3 spd auto tranny!!!!
If you you hold the brake and gas at the same time for more than 3 sec, the TQ converter will actually spin itself w/o any ATF protection. Basically, bear metal grinding.
As for leaving it in 3rd gear, that's hogwash. You'll run out of effective rpm within the powerband once reaching 62-65 mph. You'll tach out like Grand Turismo w/ wrong gear ratios on a super speedway. I had done it once and seen its result. I have also seen 2 2g NT eclipses doing this antic, and their results were far uglier w/ a much heavier car. Again, they haven't learned it yet. Wait till they get the first tranny repair bill.
I do believe modern Mitsu auto tranny can last more than 100K w/ proper ATF interval changes. If you want the tranny to last like most early or mid 90's GM sedans w/ busted auto tranny from neglect. Expect its lifespan to last between 65-80K before the thumping becomes unbearable or slipping.

Some good ideas from those guys.
http://www.2gnt.com/nuke/modules.php...ries=General#6
Some not so great idea. Just because one person can do, I don't think it can be duplicated by another or a bunch of copycatters. A 2.2 60 footer puts you as good as an average GS-T launch and floating around with a 'tegra GSR.
=====================================
· What is the best way to launch my automatic NT?
The driver reporting this technique had a Galant auto.
The same techniques should apply to an Eclipse/Talon..
- Make sure the Overdrive is off.
- Start out in Low gear.
- Power brake. This means hold down the brake pedal with left foot and give throttle to about 3000rpm.
- Launch by taking foot off brake and simultaneously flooring accelerator.
- Push the stick forward for each gear at about 6000 rpm.
The driver was able to run consistent 2.2 60's with this technique. Although the Galant has more torque, the NT Eclipse /Talon weighs less, so the results should be close.
=======================================
I wonder if the Galant is still alive or has a busted tranny. I'm thinking this car might be as old as two gen of galants ago. See this kind of stuff that they don't report. All sunshine and smiles and forgot about trashing trannies.
It's not worth the effort or cash to trash an auto tranny. Trashing manual w/ a toasted clutch, ask those Evo drivers who constantly complain about theirs within 13K.

A good version of Vfaq . . . I mostly use this to work on my talon. Similar principle and idea.
I'm just presenting info, but it's up to the individual to agree or disagree on the the principle behind the mod. By no means, I'm implying that my word is some sort of gospel. The truth is out there somewhere, and I know that I'm not the only one for source.

you'll break your hydralic actuator on auto if you race in that mode.
1st and 2nd gear is there for towing things, not for racing.
You should be able to drive your car faster than the manual if you know how to modulate your brake and throttle.
That's how you drive auto good. Don't drive it like manual.
