If GM decides to audit the dealer and find the repair was fraudulent they get penalized and have to pay for it and then the mechanic's job is on the line too.

And for the love of all things good learn how to spell warrAnty!!!

 

Why didnt you get a 2nd ECU to tune? It seems to me if you want the best of both worlds that the easiest solution. Your pretty lucky that they dont notice something like that.

Trannies shouldnt fail in this car. if your having issues it really should be covered anyways. I just thought it was pretty rediculous that you couldnt believe a tech at a dealer was nosey.

 

I had 13000 miles on my Cobalt SS/SC for 3 years before I traded it, never had an issue with the tranny which is the same in these cars. I heard ppl said they had them failed because obviously they don't know how to shift properly. Its too so bad, I'm now hearing recalls on the SS/SC's dealing with the CAT causing the car to lose power and the resorvior being cracked, which I'm assuming they meant the coolant.

 

Clicking during accel and decel

 

If you dont have the stealth tune and they scan the ecu your probly screwed. Otherwise I doubt they would send the calibration files in for examination in your case. Maybe if it was a catastrophic failure

 

all in all im just gonna remove the tune

 

How did a tune blow up the transmission? Thats what I would ask the tech, Also ask him if he has ever heard of the Magnuson-Moss Warranty Act

 

once you f' with the tune you are done. a tune can ruin an entire drive train. do you know how easy it is to have them blame the tune for any powertrain failure?

let me find that internal gm letter....

Here you go, that magnuson warranty act wont work with a aftermarket tune

Is it possible that this is axle click?

 

You increased the power beyond what GM felt was a safe level. Transmission ends up in pieces. Pretty straight forward connection there.

 

Possible. It's probably an inner cv, unless it's more pronounced when turning, then its an outer. The way he describes it it sounds most likely. It clicks during accel and decel...so does this mean ALL the time...since you are always acceling or deceling, unless idling. I bet he doesnt hear it once he reaches over 20-30 MPH.

I would just upgrade the axels and do it myself, if GM doesnt cover it, if it is the axles.

Regarding tune, in this case, I say not much of an impact, if it is the axles...more like a shitty driver, doing shitty launches...shitty, shitty, shitty

 

What about going 70mph with cruise control on there chief???

 

thats a good question! my tranny works good and shifts fine but that clicking noise is annoying. maybe its because of me getting stuck multiple times in the snow.......idk

 

Have the dealer re-torque your axle nuts. The big ones on the end of the hub. My clicking stopped after that.

 

i was thinking that maybe it could be axle nut. where the axle meets the trans, that part has up and down and left and right movement.

 

really?? lulz read what you said, then please explain what CC does

 

Really? ahhaa you so funny, maybe you should read the definition of idling

and here you go too... cruise control

 

Thats going to be your debating point? Seriously? Your going 70...so technically you are accelerating. No you're not accelerating, beyond 70, but your car has accelerated from stand still.. Add something helpful instead of criticizing the use of acceleration. If this were grammarss.net we might give 2 *****...maybe even 3, but it's not...chief

Idling - To run at a slow speed or out of gear. Used of a motor vehicle...

Now I imagine in CC your car is in gear correct? And in your original post regarding 70...70 isnt technically slow. Read your own posts of defintion before you criticize...

Anyways give some input on cars, not words, Webster.

 

I don't even know how to respond to this. SO MUCH FAIL in one post.

 

I get the same noise for some reason right now; clicking noise coming from what sounds like the front end, but I only hear it once I go above 20mph and then after 40 it seems to go away since the wind noise drowns it out.

This noise is coming whether I'm in gear or coasting in neutral. Any thoughts?

 

^^^Check you axles. Find an open parking lot, place car in reverse and drive backwards. Accelerate and deccelerate alternately. If the noise is more pronounced then its the inner cv. If you do the same test, but turn ur steering wheel to the left and right and its more pronounced then its the outer cv joint. If these tests dont help determine the issue, im betting on some extra play or backlash in your differential gears, but considering ur not even in gear and it does it, makes me thin its more like an axle issue

I could be completely wrong but with my past cars it had its always been one of the three choices i proposed.

 

^^ thanks man. I'm gonna check it out tonight to see the cause. Hopefully it's nothing too big of a deal. I can always warranty that stuff anyways.

 

If it's tuned, all bets are off, and rightfully so. Don't get your car tuned if you can't afford to lose the warranty, or buy the GMS1 kit.

 

Understandably so. If it's powertrain related, I would completely agree. Axle tick, I'm not so sure about. Hell, G35's are having nasty problems with this, a majority of the time they were improperly lubed from the manufacturer.
