2011 Camaro. Grinds when shifting from 1st to 2nd under hard acceleration

Sorry, but this is not true. I didn't even notice mine doing it until after I had the skip shift installed. The module I got was from West Coast Camaro. I had to take it out when I took it up to the dealer and it did it, with or without.

Honestly, I had a good conversation with the dealer. He explained "without saying" that there is an issue with the first gear to 2nd. Chevy "may" come out with a fix someday but they are not "investigating" it in any detail. If enough people complain, maybe they would put more effort into it.

What he told me was that once it warms up it shouldn't happen. It doesn't.
I tried very hard to get it to happen once the TRANNY warmed up. You gotta watch the gauge.

The bottom line is, don't beat it while it's cold. let it warm up.
In the summertime, we probably won't ever notice it happening because it's warm....

I just got the confirmation from my Tremec supplier that Tremec is making the carbon 2nd gear blocking ring ONLY and no other blockers. I still need to get a TR6060 trans in so I can order the updated 2nd gear blocking ring to see if in fact the new part # is made of carbon. I'll keep all posted.......

If you were closer to me I would give you mine tomorrow.

My 2011 SS did the exact same thing since new. I got the dealer to replace thr transmission @ 1000km. So far it has been good, I have only been able to put about 100km on since the replacement due to the winter weather...

I just picked my car up from the dealer. They replaced the entire transmission with a new one but the weather here sucks also so I won't know if it's any better till maybe next week! Mine had more of the notchy 2nd & 3rd gear shifting more so than grinding. I always backed off and never forced it if it didn't want to go into gear rather than grinding it by force. It might be another month or so before I have a real chance to play with it enough to know if it's better!

I have the same issues with my 2011 6.2 MT6 Camaro. Shifting from 1st to 2nd under high acceleration the transmission grinds and sometimes will not go into gear. This is very frustrating; at first I thought I was mis-shifting until I let others try it as well, same issue!! I also noticed when you shift at slower speeds sometimes from 1st to 2nd the shifter jumps to the right and you have to force second!! I will be going to the dealer this week to see how they respond to this issue, I have just over 3000 miles, and I trust GM will respond to correcting this issue.

[Vgav1221]

i have it as well an i only have 3600 miles and my tramissions mounts are apparently worn..

[6911Camaro]

Mike, who is the dealer and service manager, I would like to have some back up information when I go in this week. Thanks, you can e mail me at forklifts@chesnet.net

Plus after that issue I called customer service and complained asked them what they would do for me so they sent me a 60,000 mile 4 year warranty on top of my original warranty.

Jumping to the right is the skip shift. It's a deal Chevy made with the US government to not have to pay the gas guzzler tax, which would make the cars more expensive. Get a skip shift eliminator if you don't like it. Take it out if you go to the dealer.

As far as the tranny... Good luck... Dealers can't disobey the Chevy rules or they don't get paid for the warranty work they do. They'll eat it.. But if you get lucky and get it replaced, it will probably do the same thing.. Just warm your tranny up and you'll be surprised it doesn't happen... When it gets to 180, it's usually fine. I'm used to it, but it seriously irritated me in the beginning too... There may be a recall/fix someday but don't hold your breath..

[jtmiller92]

I'm on the second trans, warmed up or not its a grinding machine.

[MillerTime]

As jtmiller92 said even replacing the transmission isn't helping in some cases... sucks... hence why I'm driving a tahoe now....

[70Camaro2011]

Just bought the 2011 2SS 6speed been driving stick all my life and couldn't figure out why it was grinding from 1st to 2nd.. Of course the one I test drove didn't do it but I wanted a different color and that one was in the showroom... Dam I only have 600 miles traded in a corvette and now I can't even get on this thing... Anyone know where to buy the carbon fiber synchro's I don't even care if I have to pay to have them installed need this fixed or car is a gonner..Back to corvette never had this issue before.. ALSO A NUMBER TO GM TO REPORT THE ISSUE CAN SOMEONE PLEASE PROVIDE THIS..

[Chevrolet Customer Svc]

same here, on second trans , not a bit better. i wish i never bought this car!! going with the new GT-500 shelby no troubles their!!! flem

[OUTATIME]

The GT500 has the same transmission . . . with the same synchros, with the same blocker rings, with the same problems. Go check the Mustang forums.

I was looking into the Challenger they have some serious syncros on their baby's stainless steel not the brass stuff GM uses.
So given the choice and assuming I will not be able to buy an import i would buy a dodge..
Most likely as as soon as I can sell my crappy camaro I will buy a real car like a BMW.

[SSGodin]

I'm actually having the exact same problem, it doesn't happen every time, and I don't think the Tranny Temp has much to do with it. Nor does the speed or the exact RPM. I've been driving stick since I started driving, and when shifting from 1st to second my 2011 2SS/RS grinds as well. I first noticed it at higher speeds, and attributed it to the fact that I wasn't 100% use to the Hirst that came factory installed, but after 2 weeks of driving the Camaro every day, it grinds when the tranny is both cold and warm, and the rpm's don't seem to matter exactly. Under 2000 I don't usually have a problem, but over that it's anyone's bet on if it's going to grind or not.

I also have had other Camaro owners try it, with the same results. My girlfriend's 2010 2SS/RS has the same problem at random intervals. So if anyone's gets their hands on the new synchro part number please post it so we can see if their's an easier fix then getting a new tranny and praying it doesn't grind.

No grinding at all with my 2011 SS TR6060, at least not yet. However, on the 1st to 2nd shift you have to pull hard to make sure it enages fully. Hopefully this will loosen up over time. Only 1,300 miles so far.

Mine didn't grind at 1,300 miles either, started a few thousand miles later; hope GM fixed the problem on the production line so your new baby won't suffer from it.

[toast]

I have just over 4000 miles on my 2010 Camaro. It started to grind about 600 miles ago ... only under hard acceleration. It started happening on the drag strip. It was intermittent 10 t0 20 percent at first. It quickly began to happen more frequently. Within 20 or 30 passes it happened with every 1st to 2nd shift. My car is heavily modified. I am at 620 RWHP with a Magnacharger, headers, cam ... lots of other mods. My warranty was gone with 800 miles on the car.

I was absolutely not able to make a pass on the track anymore. ADM has replaced my transmission with an RPM Level VI transmission. It has carbon fiber locking rings in the synchros, 9310 output shaft and micro-polished gears (among other things). While we had the transmission out I replaced the stock clutch with a twin plate ZR1 clutch. I intend to take it to the 1/4 track this Sunday. I will update and let you all know if this completely solved the problem ... more to come ...

[chazysoccer11]

Same problem here, random grind 1-2 (not repeatable) I also get a grind while putting it in reverse, and I can reproduce the same grind over and over while putting it in reverse. Does not matter if tranny is at temp or is cold. Check my thread I started a while back.

[qniknam]

Mine has the problem randomly and the dealer doesn't give a shit, I've gone to 3 different dealers, they can't seem to reproduce the problem. So they refuse to even bother with it.
