M6 guys, what is the answer for us?
 

As I contemplate the performance future of my Camaro, I keep coming back to one problem.

The manual transmission on our 5th gen Camaros just is not up to the job.

Here is a fact for you, the stock tranny on these cars, is UNDER rated for the power output of the LLT.

All the M6 cars, except maybe the newest 2012s and 13s with the carbon syncros, ALL grind 1st to 2nd gear. If yours doesn't grind, you probably just cannot shift fast enough.

Any more power we make, generates more of a problem. The limit is right about what we can make with bolt ons.

All the m6 Forced Induction guys are having to replace their clutches. Clutch, I can understand, that is something that will need to be upgraded on every heavily modded car.


So what is the solution? A built tranny?

In addition, our gear ratios SUCK! 1st gear has a 4.48 ratio! The SS on the other hand has a 3.0! 4.48 is just too damn high! It makes the car a nightmare to launch and I have yet to see ANY M6 car pull better than a 2.0 60'. In fact, has any car done better than my 2.0? Which was on stock tires...


Help me out here people! How do we solve these problems?

I would like to know this as well......I've never grinded even when shifting fast but anyways

a built tranny would be my guess....

:popcorn:

new clutch, carbon synchros, idealg master cylinder and remote clutch resevoir is wat im doing and ill update on how that helps

Definitely keep us posted. Where are you getting the synchros from?

i got them from the dealership. you just have to make sure they order the updated ones since they changed them earlier this year

Anyone consider an out right swap?

Have you got part #'s? I've heard rumors, but not gonna believe it til I see it. Yes, please keep us posted.

Also, do you plan to have the dealer do the re-build or a local shop?

I've just added the IDEALG mod and the NH-SS fix for Hurst's shifter bushings. I want to re-bleed the master cylinder once more before I hit the 1-2 shift hard again- I figure we've got just a few of those grinds before the 2nd gear synchro is toast and nothing will fix it but a new one.

I'll hammer it by this weekend and report back.

Totally agree DarkneSS, the tranny has been the only part of this car I'm beginning to think cannot be fixed to my satisfaction. It pisses me off just about every time I drive.

I'm planning to stay N/A, so output is not one of my issues- but I was expecting to cam, etc.. But if I can't enjoy shifting, well what's the point?! :mad0259:

Part numbers if you can get them in the process of building mine so far spec clutch and flywheel.

i got the box at home so ill give you guys the part number

Please please please post paper work! Block out your personal info we just want to data.

I would but what the hell could we swap for? The SS M6 tranny won't fit right?

Crazy but it seems like a reasonable option would be to swap out for the A6 tranny from the V6 cars, reattain the rear end off the manual, and get the auto tranny completely built to be bullet proof for FI power levels.

That is what I'm worried about and I told the tech that works on my car at my dealer. He just put his hands up in a shrugging action and said that on the bright side, if it does break, just bring it in and since it is under warranty they will fix it.

After seeing our boy run a 12.1 in the V6 1/4 thread I really want to go FI but the tranny is stopping me. I'm not spending a cent more on performance until I feel comfortable about this tranny.

Flywheel and clutch are great but they don't solve the tranny problem unfortunately.

i would like to know what we can do also, i have never felt an actual grind going into second, but i know that it just doesnt feel good going into second at higher rpms. my problem i have is sometimes it just wont go into first. its like it goes a little bit in but not all the way. so i put it back to netural and try again, and most time it takes more then 3 tries to get it into 1st or i say screw it and throw it into second to take off in. If im not in a hurry cause im at a light when i put it into netural i pump the clutch a few times, and it does seem to help, or maybe its just a coincidence or just needed a break before i try again lol i dont know. its done that i think most the time ive owned this car, so it may be a clutch issue more then a tranny. :iono: either way the tranny for sure is the weak link here for manuals. i mean freaking toyotas use the ay6 lol i think with all the factory goodies we got like IRS, and LSD they would give us a better tranny lol.

I've never ground 2nd gear but I did bake some clutch learning to power brake/ peel out in a manual for the first time in this car. :facepalm:

I have a 2013 and its much smoother than the 350z i had before

I did the ideal slave, gto res and changed the trans lube to amsoil, it's much better than before, a very rare crunch at the track, but you still can't shift these cars fast..... I shift around 64-6500 now since that's where peak torque drops off.

I'm toying with the idea of having a plate made so I can use a torqueflight 3 speed for the track.

Refrain from using the brake for burnouts as it will break the clutches in the LSD, get a line lock....

Sounds like the ideal g slave is for you, not enough fluid for proper disengagement. get the gto res too, I think it was about 15 bucks.

My 60' times are 1.9xx ,clutch is holding up so far, i have smoked it a few times though.But yes the big problem with mine is 1st to 2nd shift.Trying to shift mine from 1st to 2nd under 9# of boost at 7,000 rpms is not good,i have been shifting mine just over 6k rpm and shifting slow losing alot of time.Will be watching to see if the new synchro's help.:thumbup:

Easy fix.....JET ENGINE!!!

Convert it over to and automatic, will solve all your problems!!! Easier to launch, easier on ALL your other parts and more consistant!!!

And lose the fun factor no thanks

They don't but that not why I asked. Since I will be replacing them transmission would be out of car so why not try to stop the grind.

Im sure someone will be coming up with an adapter plate to install the ss m6 into the v6

Word auto is indeed the better choice for drag racing but even with FI my car will never be a drag specific car.

My bad read that wrong.

That would work...is it possible?

If the input shafts are the same thn it's a fairly straight forward deal.

:word:.........:thumbsup:

Jay Leno's v6 turbo has a tremec, not sure how they pulled it off.

Hmmm did not know that.

Let us look into this.

A ss tranny will carbon synchros won't be bullet proof but it should handle a boosted LLT just fine. We M6 guys already have the SS rear so we'd be good to go after an upgraded clutch.

I'd expect the SS trans to hold up longer than the LLT under boost.

Very true. If the tremec would sustain 600 crank hp, that should suffice until the stroker crank is available.

:popcorn: I like the way you're thinking. (Does anybody else remember the old joke that ends with that as a punchline?).

Only the M6/RS have the SS rear and half shafts

with enough money almost anything is possible lol

Really? What do you get if you ordered an M6 with no RS? That is bizarre...

And not my problem! LOL

Are you sure? I'm pretty sure my car is a LSD.

It does for 2010-11 for sure, not sure what they've done after

Quick update on the IDEALG modified clutch mastercylinder- I think it works! :drinking:

I'm running the Hurst aftermarket shifter (I think about the shortest throw out there- but not necessarily the best one), with the regular DOT#3 brake fluid in the OE hydraulic lines and right now I've got the OE gear oil in the trans. So the new mastercylinder gets the credit. The only other recent change was the NH-SS bushing replacement- which I also recommend because it really tightens up the shift pattern on the Hurst, but I doubt it impacts the 1-2 shift that much.

Today I re-bled it (just to be sure) changed the engine oil and took her out revved the shite out of it! Tried to make it grind- shifted beyond redline and... no noise, no crunch, no nothing.

Now it's still a balky, notchy little PIA tranny. But if I can bang a clean 1-2 shift and squall those back tires for a looong time every now and again, well I might keep it bit longer. :thumbup:

I'll still be watching for an easy swap for the Tremec out of the 1LE say?

I rather replace my tranny with a home built tranny made out of butter and wood. It would definitly hold up better then out POS tranny. The fn grinds make you look like an amateur in front of people when it's really this crappy tranny. Guess it's evident how much I hate this tranny. Oh and it's soo damn notchy, doesn't want to go into first once in a while. Can't wait to replace it completely. Thinking Tr6060

Has anyone attempted to try fitting a tr6060 onto the LLT engine?
Or if they tried and it doesn't fit?

I sent a PM to one of the vendors in the Vendor Tranny section - hopefully will at least start the conversation if not get some needed info. I'll post as soon as I have something.
