Just a quick question for those shift w/AUTO's
For those of you who like to shift your automatics when racing, or just to feel the difference, where do you all start? I've been told start on 2nd, with over drive off, and then drive? Is this safer than over drive off, 1st, 2nd, and then drive? Also has anyone had problems with there tranny, when unpluggin the resistor box? I've heard that if you swap trannies with a I30 you wont have to worry about the tranny, because infinitie's are stronger? And how much help does a tranny cooler give?

u should start in first because if u dont the ecu will automatically shift for u, but unless you have the mods to necesitate going above the ecu's set shift point, i wouldnt shift it on my own. also keeping o/d off when u start off makes no differences, o/d off is just like driving with only 3 speeds in the auto trans, it wont shift into overdrive when its off, u can leve o/d off at the track, because 3rd gear is more than enough to get u past the line about the i30 trans' i think only the manual trans is stronger, and that only with the LSD

racing off the line and shifting manually is much faster and gives the chance to almost control the shift points since it doesn't shift immediately "there's like 700 rpm delay after u shift" , but putting ur shifter on 2nd is taking out that advantage because ur ecu will start from first anyways and shift on its own from 1st to 2nd and stay on 2nd till u put it on D ,,,, for the resistor don't leave it unplugged too bad for the tranny , what i did is i cut one of the wires going to the resistor and ran awire from one end to a switch in the console then a wire fromthe switch to the other end of the cut wire when i race i just turn it off and back on for the streets,,,,,,,,,peace

I shift my auto when commuting but I don't shift when running the 1/4. Shifting the auto is not helping to get lower times at all. When you manually shift, there is a BIG delay when the gears shift. There is also no need to put the car in second. Yu'll hit the rev limiter if you forget that it's in second and then there goes your time down the tubes.
I was able to run 15.6 ( and could have gone faster if I lost a couple of pounds) stock and without shifting. Whenever I got to redline, I let up on the accelerator a tad to allow the gears to drop faster. Flooring it though the gears doesn't help either.
NISMOMAXMAN: If you're going to stay auto, get the tranny cooler.

Dood, I thought you guys would have figured this out already, In Auto's 1 is first Gear, 2 is 2nd and 3rd gear, D is All of the gears including 4. Your only supposed to use the shifter when you need extra power, Dont mess around with it all the time or you will mess up your tranny, I had some experience with that, Also dont unplug your AT Transmission Pressure Sensor when your car is on, I did that once and My park turned into Neutral, 1 was Neutral, 2nd was like 5th gear in a 5spd, and D was acting all funky, then 2 days later my tranny died!!!

My car chirps the tires on the 1-2 shift when disconnected...not even close at regular WOT.
