i agree with Outrager on this one. in addition to that (but im not sure), you may also be losing a little vaccum pressure for the brakes. so braking might be a little harder as well. once again, i know you lose vaccum pressure if the engine is completely stopped, but if the engine is idling in neutral while youre cruising down that road, you might not be getting enough pressure. i don't know, im far from being an expert on this, but i'm just bringing it up as a potential problem. 2 cents ;)

 

But its a toyota it should last forever cuz its well built and high quality

 

It's been thoroughly tested, leaving it in D provides faster times. . . even in manumatic cars, with those stupid sport shifting things. Even in high end, SMG transmissions, like those used in Ferrari's and even the BMW M3, leaving it in auto results in faster times. There's a point after your power peak where power output declines. Going high into the rev range doesn't mean you get more power. . . the idea is to stay within the MEAT of the powerband.

And for those idiots who are copy-catting this idea, it all actually came about for a reason. . . from old school, oil pressure controlled automatic transmissions, I'm talkin about mechanically driven, fluid operated transmissions. In the old days, cars would often shift too early, and far from redline. Even as late as the 80's Mustangs, SOME cars benefit from auto-shifting.

Does it hurt the car? It's arguable, but it doesn't cause severe wear/damage. . . aside from cooking the tranny fluid. Can it be beneficial? Sure. . . maybe if you want to hold a gear around a turn. Does it make your car faster? NO!!!!!!

I used to do it, a long time ago, when I had an auto. . . and then I started going to the track and realized what a complete and utter idiot I was for auto-shifting. Now I have a manual.

Now if you are doing it for fun, then whatever. Enjoy. Just realize that you are slowing down your car by doing so. But if you want to improve the performance of your auto, there are definitely routes to take.

 

ONe thing about Scions, is that they have VVT-I, Variable Valve Timing with Intelligence. Its kinda like V-tech that hondas have, and if you have an automatic, you can tap the gas pedal down twice and it will just bump you up a gear. What I do when I really wanna fly is I put the overdrive off from 0-40, and then hit it on the second it hits forty and let go of the gas for like a hundredth of a sec then put it back on firm again, and the car flies up to 60+ no prob. Whoever said the Xa 0-60 time was like 10.6 seconds was way off, I can get up there in like 6 secs.

 

You gotta be running some decent boost to get your Xa to 60 in 6 seconds... What type of setup you got there???

 

I don't know if the auto tC is different (I have a 5 spd) but my last car was an auto Nissan 240sx, and if I just floored it it would accelerate pretty fast, and ____ at redline. So unless the tC auto tranny is very different, I don't see how it could ____ faster.. if anything, it would be slower due to human error.

 

I know a guy on another board who has been driving his auto WS6 like this for a while. Actually he just hit 11's yesterday. I asked him a while back if it hurt the trans, and he said it drives the same as it used to. Plus the car is much faster when you shift it maually. Here is his vid. Keep in mind, this guy has been trying to get into the 11's for over a year.

The only time i shift my auto is when i need to merge with traffic, or messing with sombody in the next lane. Like i am barely touching the throttle but i put it in two so the it will be in the appropriate rev range. Intead of it shifting itself all the way into over drive, then when i hit WOT shifing it self down to 2 anyways. As soon as i am at WOT i just pop it into drive and it is fine shifting on it's own (yes it takes the same amount of time for the tranny to shift itself as me shifting it). All that happens when you shift an auto is telling it WHEN to shift. Either it will or it won't because it will lug the motor. And no it wont hurt the automatic. A well built automatic is very stong.....but just like a manual if you abuse it, they will have probs. An auto matics starts slipping, a manual will burn a clutch. Bad thing is with a manual and you drag it consistently you WILL fup a shift you can bend a shift fork or grind down a drive gear, hurt the motor....or just shift to slow. Honestly the only time i lose to a manual is off the line because i cannot rev my car as high to get into the right rpm to launch the car. And yes....power braking an auto will hurt it IF do it consistently or for a long time. It's like slipping the clutch holding the brake and reving the throttle, it will burn your clutch or warp your pressureplate even the flywheel if done long enough. Only time a guy will beat me in a roll on race is if the guy is PERFECT on his shifts, reason for that is a manual you have to let off the throttle to shift(if you full throttle shift you are just askin for a blown clutch) this auto matic does not let off the throttle it uses it's internal clutches for the shift at full throttle. And yes everytime you let it shift at full throttle it jumps forward. Will it 'eventually lose, yes ,due to the heavier weight of the auto but that is like a 120 mph freeway dog fight. From what i read on a toyota site is that the auto has a "lock up" torque converter, where there is no slip in it above a certain rpm, so the only thing i am down on is my weight and the launching. Give me a high stall converter and heavy duty internal clutches and a diet....and i am ready to detroy. The key to the auto is constistency. it will do the same thing everytime, that is why most of the top brakcet drag racers in the world use an automatic. hey and i have nothing against manuals my other car is a 4 speed and i love it! SORRY FOR THE NOVEL.....JUST HAD TO GET IT OFF MY CHEST.

don't get me wrong a tc is not a drag car and i am not pretending it to be. And as far as road racing is concirned and auto cross when you have to shift up and down alot......yeah an auto stinks.

 

Reading this post just makes me realize how lucky I am to have a dad that has only owned stick cars his whole life. And when it was time for me to learn to drive at 13 years old i learned on a stick car. And when I got my learners permit At 15 I drove his car(which was stick) And now at 21 I have only owned stick cars my whole life. So for those of you with automatics because you cant drive stick i feel bad for you man...im here to give out free hugs to make you feel better if you want.

 

i drove an 88 honda accord for my first car and it was automatic...good for my first car cuz it helped keep my eyes on the road and have less distractions. my second car is an 82 Mazda RX-7(107k miles)...and hell yeah its a stick. i love it. i drive it hard and loud all the time. its a lot of fun...you better believe what my next car is...06 Scion Tc MT...ordered it today. yesss...

 

Like I posted, very few cars benefit from this. . . mainly ones with archaic auto trannies.

 

First off, it's VTEC, n V-tech. that's a phone company, I think.

And no, VVTI is not like VTEC. VVTi-L is the equivalent of i-VTEC

VVTi similar to honda VTC
VVT-L is similar to VTEC
VVTi-L is similar to i-VTEC

Something like that. And VVTi doesn't really "kick in"...it operates continuously at all rpms, which is a good thing.


and how did you get your auto tC to run 0-60 mph in 6 seconds? I'm assuming you're boosted or heavily modded?

 

It's even better, according to his profile he doesn't even have a tC... he's got an xA lol

 

hahah

 

this is a retarded post. ____in ricer auto shiftin idiots. get a manual if your gonna shift. i think that people who shift autos are dumbasses. it DOES ruin the tranny, and it DOESNT make the car faster. i have worked for my families shop for almost 10 yrs. (high performance imports) so i think i know a littlebit about imports. i DO engine swaps, tranny swaps, turbos, superchargers, suspension, and we have a in house dyno. i KNOW how to TUNE a car. i seen a tranny that has been shifted manually, its trashed, compared to one that shifts normaly which only shows normal wear and tear. theres a reason they program the ECU the way they do for autos. treat it right. you WILL void the warranty manually shifting a auto, and if you think they wont know your wrong. if you dont care, neither do i, your the one looking like a retard when people see you shifting a auto

 

^^^^^ and theres no such thing as VTC from honda. just to let you know. but please if im wrong tell me what cars have this magical engine. its either VTEC, or i-VTEC.

 

i'm no honda expert, but i think youre wrong (no offense). i happen to know that there is such thing as "VTC" from honda:
http://world.honda.com/automobile/overview/index.html.
it's a reference to something un-related to "vtec". simply put by honda, "i-vtec" is a combination of both "vtec" AND "vtc"
