Yup 725miles on the car and today went to pass someone and when I shifted at 5300rpms it would not go into gear! So I tried it a few more times during the day and it would happen almost every time if I was shifting at 5K. It fells like shifting into a wall. It eventally gose in, but I have play with it for a few seconds. Has anyone else come across this?? Feels like a bad syncro??

I guess if you wanted to try it you could try rev matching at higher RPMs and see if it glides in more easily. Though if the syncro is really hosed that might not even work. I'd get it looked at but you could try the rev matching idea if it'll make you feel better :). Sound to me like that's more than likely what the problem is but with only 750 miles that'd be terrible luck.

Permafried-

Yea there was 300miles on her when I bought it so who knows what happened. I'm so pissed. I wonder how long this will take at the dealer? Also Im worried they might put in a new non LSD trans by accident! I never trust dealer techs.

Well hopefully they wouldn't have to replace the entire transmission unless it's REALLY screwed up, couldn't they just replace the gears and therefore fix the syncro at the same time (sorry still fairly new to standard trannys)? If they do have to do the whole tranny just make sure they record somewhere on the work order and part order that it's equipped with a LSD...hope it's covered by warranty I don't see why it wouldn't be.

I've had the same thing happen from time to time, but not usually while downshifiting. It's also third gear, it seems to be very sensitive to RPMs, moreso than the other gears, like sometimes (not always on mine) you have to hit it JUST right or else it won't go in. Hell, it's under warranty make them check it out and make sure nothing's wrong with it. If it still does it after they look at it, just play around with your RPMs and find out where it likes to hit 3rd.

BTW, if they do have to order you a new transmission it should come up when they enter your VIN that you have the LSD so you'll get the right part.

so umm why r u takin the car up past 5k with only 700 miles? break the car in meaning engine and trans. 5000miles recommended. seriously.

n e ways were u shifting from and your probably shifted in to a higher gear and forced it in so kaboom. probably went from say instead of 3rd to 4th, and went from 3rd to 2nd, so kaboom. n e ways dont see why you were takin the car up that high of rpm in the begining. engine and drivetrain nee to break in properly.

5000 miles?!?!
hahha
you sound like a chevy dealer
its been proven, for a new car, 500 miles of varied throttle, then ease into full driving
engines comes broken in from the factory
then the car gets tested on a closed course

my 3rd gear is weird sometimes, it grinds occasionally and i cant figure out why

broken in from the factory, from the factory all they do is put few hundred miles. the car needs to be babied the first few thousand miles, not neccessarily 5000 miles but atleast enough for 1 full oil change ie, 3000 miles. not only chevy dealers say that but every automotive mechanic says it.

how much is a syncro?

Not sure, but the tranny has to come apart.

they break in the engine fully, all you need to do is a 500 mile break in and that should be fine, i just woudlnt be racing 24/7 til 1000 miles
new technology changes all the old rules about break in and oil changes every 3k

How many miles does john force drive his funny car before he makes a full throttle run? Drive it like your go kart when you were a kid. All's I can say is 5 year 60k on powertrain. lol

Eddie, your a moderator and you don't know what that manual says?!. The factory manual says that no break-in period is needed, and the first oil change is no earlier then any other, if you wait for that you will be pussy footing around town for 10-12,00 Km's. Yes you could do the first one early if you choose but i think i will listen to the factory reccomendations before somebody on a website. Please in the future if you don't know what you are talking about, don't give advice. We are talking about brand new cars here and i am sure the factory knows more about it then you do.

Actually the manual suggests a 500 mile break in period where the engine isn't driven at a constant RPM level for a long period of time. There is no mention about any oil changes during break in.

I go by the oil life system.

And the only real reason they suggest varied RPMs is in case you have a problem with lubrication and you just happen to be driving for long periods of time at that exact spot which would most definitely be bad :lol:.

It seems with the precision of newer engines (as Tiny pointed out :)) it's not as big of a deal as it used to be. I babied the hell out of my LS until somewhere around 4900km and then I started getting on it a little bit more...I couldn't hold out any more. Ever since then I've had a hard time NOT hammering it in second gear whenever I get the urge or someone is being a jerk and won't get out of my trunk. I still will not go by my oil life system...it was at 53% when I hit 5000km which means it would be good until somewhere around 10,000km...that number on a new engine makes me nervous. After a year or so I'll begin going by the oil life system but not right away...I know it's there for a reason but I like to be difficult :).

Any word on what was wrong with 3rd gear yet?

The first thing they do with your engine at the factory once it is built is start it up and take it all the way to redline. You need to read up a bit Eddie ;)

my third gear does that sometimes too. even upshifting... there are a couple times where it just doesnt want to go in. you get used to it.

I seriously suggest you take it in and get it looked at. Mine was the same way and it was a bad linkage cable. Someone else on the site had the same problem. It's under warranty, take it in and have them look at it...this seems to be a recurring problem. Mine started like yours and I was going to "get used to it" too, but then the same thing started happening in other gears so I took it in and now it shifts incredibly smoothly all the time, no more not going into gear.

Getting back on the thread... My car has 3000km and punch the throttle every chance i get. I also have problems with my 3rd the other day i shifted at 5500 and my car cut out and caution light came on and idicated (engine power reduced) some sensor went off not sure wich but iall i can say is that its a sensitve one that needs practice at high rpm.

My third is a little tricky sometimes, maybe it is common

hey so what happened to your car that just happened to mine i have to shift to 3rd between 3000 and 4000 rpms other wise it grinds and i cant down shift from 4th woth out first putting it in second i dont let out the clutch just put it there and up shift mine going in on tues to get looked at

Third was always tricky in my Cavalier, even others that had cavaliers said mine was worse... maybe it's a Getrag thing

Third is tricky in the SS/SC too and it doesn't even have a Getrag, it has an FGP tranny.

Ah.. I'm sorry I thought it was a Getrag, my mistake. Still learning on the Cobalt.. new car to me. Maybe we all just suck at shifting into third, haha, jk.

I had the same proplem when trying to upshift fast. Solution...I found that I wasn't pushing it over far enough and it was jamming between the gates. I was used to my sisters eclipse that has shorter throws.

I guess it could have been the linkage also. I had to take it in and have the dealer rebuild my shifter. For some reason, after the knob popped off and wouldn't go back on, when I tried to go into reverse the shifter wouldn't go. Then it wouldn't go into first. I had to rip the boot off and pull off the linkage for the reverse lockout. Other wise I was stuck in the middle of my street. I was trying to parallel park at the time.

EDIT: I found the pushing over further trick worked before I took it to the dealership.

I used to miss third alot, but I am used to shifters that are attached to the transmission!
It's a whole nother feel using a linkange shifter.

As for syncro replacement the most expensive part is the labor, Most syncros are pretty cheap.
