Manually shifting an auto. Ok to do often?
Just watch those Mets comments....
Phillies do all the speaking for me

it depends on the car.
basically, the lower settings on the selector open or close valves that limit what it lets the car do. in other words, you're not picking a gear, you're telling it to NOT go into the next one. when you upshift, you force the car to shift because you slam that valve shut. you should never shift a normal automatic at WOT (or any car).
also, most stock cars, putting it in drive and keeping your foot on the floor is just as fast as dicking with it.

Phillies? Sorry about that. You don't have a leg to stand on. You are still the losingest franchise in sports history, You haven't played well this year, you didn't play well last year. You did not win the division last year, we lost it. If we play .250 ball, we win by 4 games.
lol... I do not want to get into a baseball argument now.

youre not really benefitting from it. When you drive an auto, it shifts through all the gears for you. Thats the point of them. Trying to manually shift an auto if anything will make it slower because the tranny takes time to adjust to the gear you switched it to, not to mention the increased chance of slippage. If you wanted to shift, should have gotten an manual. You could convert the tranny to manual, or electronic shift.
2. Read the original post, it's not my car, and my daily driver is a stick.
Thanks for the advice guys, i'll continue to upshift then i guess!
"fact of the matter is, take 2 cobalts, give them the exact same mods and exact same hp, with good drivers, the manual will win every single time. and you can't argue that, because it's a fact, not an opinion."


Except for those "missed"shift runs -- won't win those times

and that too is a fact!
Would make more sense for stick lovers to avoid threads by autotranny owners. I promise not to give advice to stick owners.....

let me rephrase that. the manual cobalt will always be faster, taking driver error out of the equation. a shitty driver in a very fast car can lose to cars it should lose to. doesn't mean the car is slower. it just means the driver sucks. i'm not knocking automatic cars, i've had my share. but that's the way the cobalt is.
If you want to enjoy it, and you dont care about it breaking, feel free. Like I said though, its not going to make it go faster than if you just kept it in drive. You could tune it to make it shift at peak points, but if its not yours then dont worry about it.
but the argument wasnt over preference, it was over functionality.
no one begrudges someones choice of an auto.
its when people try and argue that an auto is better in terms of pure performance that people disagree.
I beleive that they are equal.

Just a question.
When 'my friend' manually puts the trans in L and uses his ShiftPlus on 2, you can hear what sounds like a fluid 'pssshhh' when it shifts.
The sound is slightly noticeable on the 1-2 shift (WOT) in "L", but is most noticable on the 2-3 shift (WOT) in "I"
What is this sound? Is it bad? My friend rarely runs the car with mode II on, but when he does, you can always hear the sound.

Hard to diagnose over the internet...you sure its not the tires spinning? It could also be a loose serpentine belt -- they can make an odd noise at the shift when they are loose because of the change in engine speed. There is also the possibility of converter chain "slap".
I'll try and get a video or sound clip for you.
On my SUV I can tell when the serpentine belt needs changing because when I "get on it" the belt will make a fast "Swish" sound at the shift -- and it sounds like a fluid type noise. When the belt starts to get loose it only makes this sound when in WOT at the shift points too. The first time I heard it I thought it was the tranny slipping. That is the only thing that comes to mind from the noise you described.
Hmm, i'm not sure if it's the belt or not.
The 'balt has just under 2000 miles on it, so it's barely broken in still.
I really only notice it in the 2-3 shift, probably because all I hear on the 1-2 shift is tire chirp!
