Do these 2.4L sports have an Overdrive?? if so, how do u take it off ... or is that only what automatic trucks have lol

 

Most auto transmissions have it, it just changes the input on the planetary to give a overdrive ratio. There is no taking it off. Why do you ask?

 

you should research what an overdrive gear is...because there is absolutely no reason to want to remove it

 

why the heck would you want to make yourself slower....

 

I lol'd at this thread. If you remove overdrive your removing 4th gear thus making your car slower and killing your gas mileage with it. If you really don't want it just put the car in I instead of D. Here is an article on overdrive: http://en.wikipedia.org/wiki/Overdrive_(mechanics)

 

im not trying to remove it... alot of vehicles with overdrive have a bottun for turning it off for going up hills and ****... my way to and from work consists of 15 miles up and down hills... and i hate the car constantly downshifting

 

that is precisely what the lower gears are for on our car and why you can select them.

 

you can select the lower gears?? i'm sorry i'm dumb when it comes to auto, i've had manuel everytime b4 this... there is no 1 - 2 - D - N - R - P theres no numbers on mine... theres like a I and a L or something

 

same with mine. there the same thing. here ill explain.

first. know that i belive hunter89 made a good thread somewhere thats really detailed on the auto.



ok


let me begin.

It is impossible to do real damage with ur auto. even in L it will eventually shift to save your car.

L/1- will stay in 1st till 6k i belive. Also turns off TC
I/2-Tranny will shift at slightly higher than normal RPMs 1-2 with increased line pressure but traction control on. Overdrive Can be used in I.

 

so i should use the I when going over hills?? seems like 2nd gear would be a little low for going 55-60 imo but maybe im still not understanding idk

 

honestly just mess around while driving. YOu wont do any damage if your stock and your tranny is not tuned or has a shift+ on.

Just dont go directly to L. GO D to I to L

yo can go Directly to drive anytime

its hard to explain. you need to get a feel for the car/tranny and most of all the engines power band which is a bit high in the RPM range

 

Thats strange I thought I/2 only went through 1st,2nd,and 3rd gears but not overdrive. If what you say is true than it would if you redlined to save the tranny.

 

U may be right.... Actually.... welll


I cant think right now....


uhhh CSSnet.... does I allow overdrive???


I could have sworn i can slam down my gas in I and get overdrive to kick,

it would shift to save your tranny


I know for a FACT thats true.





hehe

 

kay now, last Q , does it hurt the car driving with the I insted of D??

i just went and drove it useing the I option and i love it... but i dont wanna hurt the car... it didnt even rev up that high, just insted of shifting to OD, it stayed at like 3500 - 4000 rpm at like 55-60

 

No it shouldn't but you'll see your gas mileage go down the tube lol

 

^^Correct.

"I" is full automatic without OD. Your tranny will shift up 1-2-3 at slightly higher RPMs than in "D"...and down shift 3-2-1- automatically as you slow. Your gas mileage will go to "Heck" though simply because your engine will be revving higher than is necessary.

Think of it this way: "I" is not "2nd" in the Cobalt.

 

idc bout gas mileage, i just wanted to make sure i'm not going to burn out the tranny or nething, and i like how it downshifts aswell, sounds cool w/ a aftermarket exhaust

 

i believe it says you can daily drive with it i "I" in the manual actually

 

L=drag racing(start off with) I=spirited driving D=everyday normal driving

 

in my experience, using I will keep your RPMs around 3krpms when on the throttle, and above 1.5krpms when off the throttle. It will not go into overdrive. L will not shift from 1st to 2nd until redline, and will downshift to first if the RPMs will be above 4500, and downshift to 2nd (assuming you're going from D/I into L) if the RPMs will be above 5600 after the shifts

 

I was waiting for you=)

 

here i am! to the rescue! lol


^^ yea, that was kinda gay...but im really bored

 

so its safe to use the I option then?... idk why i'm so paranoid about it , but these cars tend to have the stupidest problems

 

its just as safe as L, D, N, R and P....

 

I like using "I" when i wanna drive more agresively. I consider it sport mode while "L" is drag mode. Also i find since i'm modded I mode works even better now.
