I have a H-series tranny with a CC twin disc setup. When everything is cold the trans has no problem going thu the gears. After driving a little bit when at a stop when I go to put it into 1st gear it always grinds. I have syncro tech syncros in the trans as well and just had it rebuilt no less than 500 miles ago. Do you think my 1st gear is taking a crap or is it a clutch issue?

 

i had the same problem jamie, i can send you pics of my syncro when my twin was junk. its from the clutch not releasing all the way. go into 2nd, then first and im willing to bet it will go in fine. this is bryan btw. comp is one of the worst things i have bought for my car.

 

I have already replaced a set of carbon syncros because of that clutch. At least I am thinking it was the clutch. I had the pedal adjusted wrong and it toasted them. I put more play in the pedal since my last tranny build and the same ish is happening. Any other options that you know of that we can go with for a clutch? You would think for the money paid to CC that they would give you a product that preforms properly.

 

Yeah, its the clutch. Give me a call tonight and tell you the whole story lol. Cc is a joke.

 

I wonder if Competition Clutch will chime in. This clutch has been nothing but a nightmare from day one. This is my first twin disc and on the instructions they say the clutch's are labeled make sure you put the one that says "tranny side" on the tranny side. I did that. After getting the whole thing put back together I couldn't engage into a single gear. Long story short comp clutch put the stickers on the wrong discs. Good thing I didn't pay a shop to do the work otherwise I prolly would of been eff'd. Comp clutch said "sorry" and sent me a t-shirt.

 

Lol at least you got a shirt. I will show you my disks they tampered with and said it was my fault. You can see the vise grip marks where they bent them. There is a thread floating around here that i made a while back. With the pictures and emails. I still have them and will keep them forever just to show people in person that I'm not joking.

 

Man that's such B.S. For the kind of money you pay and they treat you like that is a absolute shame.

 

Have you verified that the release system has enough travel to properly disengage the clutch? You can check this at the clutch fork with a buddy pressing on the clutch pedal.

Do you have a clutch stop installed? Repeated over extending of the diaphragm can lead to ultimate failure.

Do you have time and are you willing to sent the clutch in for inspection? Although the twin disc assemblies do not carry a warranty I have been able to help out our users by updating their assemblies and no or very little cost. (such as MR.johnson where I was able to update the diaphragm assembly to new parts at no cost to him regardless of the other issues he was having with his system.)

and im still not able to get the clutch to opperate how it should, the thicker disks that i bought form you are now making the fingers on the pressure plate sit in to far. and you told me over the phone the parts you replaced for "free" were the wrong parts to begin with and were for the old style top hat. no?

 

please honda-tech, explain how hanging a trans off a disk bends one puck and leaves a pliers mark...

 

Dominic, when a part fails and its my fault I take full responsibility but its not this time, other companies we have worked with go out of the way to help. But this has been a nightmare from start, i hate to bash on cc everytime a thread comes up but its bullshit. Send my money back, you can have this "rebuilt'' clutch back and cc will never hear from me again.

 

No I am not willing to keep beating a dead horse. If I am going to waste my time AGAIN ripping out the trans I am not going to try to get this pos to work. I would much rather spend my money on something that has been proven to work. Pay for shipping back and fourth, pay for parts, the time putting it back together again just to hope the problem is fixed. I paid 1500 bucks for that thing. You guys should eat ALL the cost.

 

Only issue I see is this method won't get the problem solved. Nothing is wrong with asking questions, but there are several variables here.

Manufacturer issue and install issue. Hope you get it resolved soon because there are a lot of people who have never had issues with cc including myself. Best of luck to both of you

 

Ahobbs, did you see the pictures? Please tell me how that's from hanging the trans on the clutch... Bending one corner of one puck on each disk? No.

 

I'm on my phone I can't see exactly what you are saying. By I don't understand why they would do that to Thier own clutch. It makes no sense whatsoever.

 

my clutch had the wrong parts to begin with, they said it was send with parts for the old style top hats and needed to be changed , it never worked right, the disks i needed to buy to "fix" the problem were 100% different and look like a much thicker plate, more pad area and beefy hubs. a clutch with 2000 miles and under 4 passes at the track should not **** out... i wish dominic would chime in to explain how a single puck gets twisted by hanging a trans off the disk, the hub would be bent in the disk not just a single puck twisted...

 

you can see the pliers mark!! lol.

 

We are having similar issues with our brand new cc twin. I chalked it upto not having the pedal stop and/or free play properly adjusted.

We just got the clutch in it last night so ill try to get some more time with it.

 

still waiting for dominic from CC to chime back in.

 

Exedy ftw, no clutch stop required, and shifts like butta

 

I didn't know exedy made a twin disc.

 

Exedy is not the answer

 

what is?

 

Bryan you are absolutely right!!! I raced at import wars this weekend and when my car was on the dyno this past friday we tried the good OL 2nd to 1st and it went into gear with no problems. BUT now 4th and 5th gear get that grind going into each gear. It really sucks because this is the 2nd set of carbon syncros that I put in this year. This is also weird... This year in the begining of the season I made a pass at the track and because my car did not have a IAC valve on it, it would die after a pass at the track. So, before the turn around I would always have to re start my car. This one time I did so by releasing the clutch and it grabbed so bad it completly shaved the teeth off 2nd gear. When we opened up the trans the carbon syncros on every gear were trashed. Dude from synco tech said he never saw a set that was as bad as mine. This clutch has costed me $1500.00 then another 2500-3000 bucks in dammage to my transmission. Not to mention all the time wasted taking and puting it back in. Thanks comp clutch makes perfect sense now.

 

The Clutch didnt break that transmission dude. And second is KNOWN to be weak in the H trannys... Usually the M2F4,B4, or A4 moreso than the y4, the ratios and tooth count is different... M2Y4s I always broke 4th (And a couple seconds, but ALWAYS fourth).

By the way now that i Look, thats third gear thats broke... IS it an H23 trans by chance(M2S4)?

Any TQ above 375ish thats hooking well s going to seriously strees the set. COmpounded by weight (Which is what makes my car more problematic, its heavy and makes WAY more TQ than that) I started breaking **** regularly at around 375-380 TQ... WHich was my pump gas tune, so it happened alll the time before the gearset. Even with the Tilton FCV. It helped the Hit on the gear off the shift, but RAW POWER is what breaking the teeth. NOT the clutch itself. A FCV MAY help though. I have one.

To make an educated judgement I need to see the sleeves, and the inner linings of the syncros, and super close up od the outer edges of the blocking rings.

That number 3 looks like its just seen its limit of hits on it . Ive ONLY broke 3rd in H23 trannys

Stock gears wont last long at the track, especially if youre hooking andf getting out. Ask me how I know ;O)


Ready for a gearset yet?




Ive had issues with my comp clutch (Specifically disk splines) but never anything but that, but... This set of disks in it right now is working great. If you know anyone looking for a clutch, mines for sale for 700. I got a new deal coming :O) Complete.

PM if you know anyone looking for a Complete twin with TO bearing and everything.
