AY6 1st to 2nd Grind

[c_LoW29]

My car currently has about 6000 miles on it, I am bringing it in tomorrow for them to look at my transmission. As many other have been stating when shifting from 1st to 2nd at high rpm's they get a grind when engaged in 2nd. I wanted to find the TSB for this issue so I can have additional information. If you have the TSB please let me know so I can bring it with me. Any help would be greatly appreciated.

Having had my transmission replaced for this same reason, I don't think there is a TSB on it (yet). Last I heard was GM was investigating the failures but had not taken action yet on an actual fix.

Well im bringing my car in for the 3rd time this time im taking the tech with me and im driving to show him when it happens and hopefully I wont have to wait forever for this to get fixed I dont want to have to pull the Lemon Law but if my car falls under that category i wont hesitate to do so.

Just to update anyone who has looked over this thread:

They are taking out the transmission and replacing the clutch and inspecting the transmission. As soon as i get some more info on any further issues i will update it here.

So yesterday the dealer calls me and the service manager tells me that they are ordering new synco's for the car. So I ask him if that is what he determined the problem was after taking out the transmission. He tells me that he hasnt removed the transmission that they read over some bulletins and that was the cause of the problem on another vehicle. Then I ask him how do you know if you havent inspected the transmission. He tried to tell me to come bring the rental back and take my car until the parts arrive and I deny to pick up my car until it is fixed. I am not going to let them reset the clock on the time it has been at the dealer. This is really discouraging. If anyone has any information that would help me regarding lemoning the car ect. please help this situation is moving me much closer to getting rid of the car that I wanted for 4 years.

Why is everyone so adamant about using the Lemon Law rather than just letting GM fix these issues under warranty?

When you have been to the dealer 5+ times in a 5 month period for different issues then you will understand me.

If you have dealerships like mine they wont fix crap, tell you cant hear any noise, operating as designed, bla, bla,bla, and your car still is not fixed, multiple calls to customer care, multiple calls never returned, many tylenols later the lemon law looks like a steak dinner being handed to you by an angel! Im trying the same thing!

The first issue I had I tried using that customer service line BS and they dont help. They are just there to hear you complain and say stuff like dont worry Sir we will take care of this I know what your going through, you have a really nice car though this is unsat bla bla bla. I dont want to Lemon this car I love my car I have been wanting it for a long time but I defenitley wont stay with a long ass loan + a bunch of issue for that I would have bought a used car cash.

I am starting to get this issue and notice when I take 1st to about 5500 rpm going into second. I've had it grind 4 times. update: has occurred 7 times now and becoming more frequent

[afireinside]

I have a low RPM issue I cant get a good first to second shift sometimes ill have to put it in neutral and "shake" the shifter and try again.....

[DyerCamaro]

I Had mine grind on me going into second the same way. For some reason at high rpm its physically difficult to shift into second gear, so when shifting quckly you dont get all the way into gear and get the grind instead. All the other gears shift smoothly but I have to concentrate to make sure you're completely into second. It seems like at high rpm the engine torques the transmission a small amount forcing the shifter up against something making it difficult to shift into second. I don't know what to do to fix it, but 2nd gear is a pain in the ***. I wonder if it could have something to do with the shift skip.

[acuraelin]

I had my 1st-2nd gear grind couple of times before at lower RPM and I thought maybe I should pay more attention make sure it's in. I just drove the car a earlier and this time is about 5500 RPM and it grinds. I tried it again to make sure it's not me and it did it again which is why i'm on the forum to see if it's just me or it's a common problem with 6M. I have a 2011 6M with 3600 miles.

[Trey42590]

Same problem here! Guess I'm going to have to take it to the chevrolet place....

[LT1Jeep]

i always thought it was a hard shift from 1-2, at first i just figured everything was new. Now the grind is getting worse. Esp at higher rpms and under load trying to do it quickly it goes into the first part which should be the syncro mesh but the gears grind horribly. if im gentle on it i can get it in no prob. also a 3-2 downshift can be tricky and minor grind too. ill gonna call on monday to bring it in.

I think this and the pcm not having software yet is the biggest deterent for me not buying the v6.

Any updates, Have not gone to dealer yet but mentioned to my salesman who blew it off- GF thinks im crazy as she cannot "replicate" the problem andl likes to rub it in my face but she doesnt try to shift as fast as i do - What concerned me, is I think I have smelled clutch burn - I have read in other posts, that clutches are getting burned out quite fast and full tranny replacements are happening due to the grind. can anyone comment?

If you can reproduce the issue, then take it to the dealer. I'm assuming your GF isn't an ASE certified mechanic that works at the Chevy dealership? If not, then it really doesn't matter if she can replicate it or not. On my original transmission, the problem was very intermittent.

Your salesman probably doesn't give a rip if you are having problems. The car is sold and he got paid. Everything after that is the service department's problem.

If you are smelling burning clutch then you aren't shifting right.

I have had the 1-2 grind prob 7 or 8 times on my 2011 SS with the factory Hurst shifter. I told the dealer about it. The "Camaro specialist" replicated it and is ordering new synchros etc. Hopefully it fixes it.

Only one time but it was clearly burning ill admit i ran her pretty hard. Does anyone notice and the only way I can explain it is ... bleeding into the next gear. Foot is all the way in on clutch and i release in what I feel to be the right ime but feels and soums like 1,2 and 3rd gear bleed into each other when shifting like rev laggy rev to over rev bleed

we got a half-ass transmission!..it's actually made by aisin in japan with some components being warner components!..it's a hybrid!....lots of people reporting 1ist to second grinds, and also 2nd to third grinds too..hope they send out a service bulletin on this!

[clarrkkent79]

And I thought I was just shifting like an idiot. I've had my 2SS for less than a week and have grinded 1st to 2nd shifts more times than I've grinded gears in my 12 years of driving manuals.

Due to this and the idiotic skip shift, I've been starting from a stop in 2nd when possible.

[ponbigi]

Still working on getting the TSB # but not sure if this will help and could use a little help on this one myself. They are replacing the following parts. FORK, RING SET (2), 2ND GEAR, SLEEVE AND OIL (ASSUMING TRANNY FLUID) Anyone with more knowledge then me care to take a stab at what those parts are (other than 2nd gear) and if I should be concerned and step it up to get a new tranny?

[c_LoW29]

Just to update you guys on my initial situation the problem persisted after having the car out for a week getting the sycronizers replaced. I tried to bring it to the same dealer again and they refused help saying that they couldnt duplicate the problem and that if i didnt believe them I could bring my car to another dealer for a second opinion. That being said the lawyers are involved and they have already contacted GM. I will update you on future changes of the situation.
