Now im having second thoughts about buying an act clutch since too many ppl here complain about problems

 

i wonder if the time to do it is now. Ill ask them if they can put in a new clutch while its out for a very small charge. man, thats a crap load of money that i don't have...but i don't want this headache later.

I think they are gonna pull the tranny apart and put new synchros in it....atleast im going to push them to do it.

 

I'm having almost the exact same problems as you! Ill give a little history:

I fried my clutch got clutch replaced with ACT. After my clutch install the installer said sumthing is wrong with the tranny. My car didnt go into 2nd, if i would be idling and put the car in 2nd and slowly let go of the clutch 2nd would just pop right back out! Or if im driving and put it in 2nd it would grind. So i took it to a tranny shop. Rebuilt my tranny, and now when I shift in high rpms my car doesnt go into gear. Mainly when going from 3rd to 4th is when i really notice it. When I press my clutch my clutch makes a loud sqeaking sound, AND when im downshifting from 2nd to 1st i also hear a whining sound! Also my car is not as fast as it used to be! Sorry for highjacking your thread, just thought since we where having similiar issues i didnt wanna make a whole new thread.

 

How many people are having problems with ACT clutches??

Could it be that the ACT clutch actually performs how it is supposed to, but Mitsu's tranny is a piecce of crap?? That's why the stock clutch burns out so quick? It's a cheap band-aid for the real problem...

 

the stock clutch goes out so fast because its just weak and lots of people can't drive.

the ACT disc is heavier than stock, therefore harder to shift fast at high RPMs. It holds power good, but the shifting is just sub par from what ive experienced so far.

 

The stock disc goes out because the linings can't take the heat either and they break down and lose material prematurely because of it. The linings of our disc are a little heavier that stock due to the steel backed linings, but it is a minor difference compared to some designs. "Don't throw away the baby with the bath water" as the saying goes. It is not like our clutch is that much different than stock. I have addressed the shifting issues on other threads which I am not going to rehash here, but basically the shifting shouldn't be worse than stock unless the hydraulics aren't adjusted properly, the pressure plate is damaged, the release bearing isn't installed correctly, or the addition of other mods that drastically increase torsional vibration. The most common problem is adjustment but I am sure that is not all of it.

I wish I could get into this deeper, but I am short on time because I am packing for a family camping vacation. One of the rules of the house is "If mom aint happy, nobody is happy" so I go to get back to it.

 

I should clarify my earlier post. It isn't an ACT specific problem. single disc clutches have this tendancy. If you have a twin disc, then you wouldn't have a high speed engage/disengage problem.

I loved my ACT until I started putting out more power than it wanted to work with.

 

I adjusted the pedal where the clutch engages at the top of the pedal instead of mid-bottom and it made my high speed/fast shift to third much smoother. It still grinds 4th, but i think that might be a tranny issue.

I only shifted hard/fast twice so im hoping that my results are a sign of things to come with the clutch all the way at the top....now i gotta completely relearn my shifts.

 

How much did you turn the rod? I'm almost to the top with no thread on the rod and still no help. I wonder if I can adjust it some more

 

Ummm, you adjusting the rod didn't move your clutch engagement higher up on the pedal? I turned mine a bunch, ill try to take a pic of the rod this afternoon when i get home.

Are you saying your shifts still grind, or the engagement didn't change positions

 

Engagment is up top and no grinding but I can't quick shift at high RPM. Sometimes the shifter will get stuck during shifting and cause a misshift as well

 

The pedal should be dropping or rising in comparison to the foot rest. Drop it to roughly a 1/2 in higher that the rest. It should be good there.

 

One other thing. Mitsu trannies are weird. They don't all like to shift at high rpm easily, you can't powershift them at all. You can try to replace the fluid with GM synchromesh, get a better clutch, or shift at slightly lower rpms. 6-6.5K is a safe shift, about that with an average clutch you will most likely experience a problem or two.

 

FWIW, my clutch pedal rests higher than my brake pedal by a good bit now.

 

I had GM synchromesh and change it out with new synchromesh and still having problems. I use to have this problem with the stock clutch but after the fluid change and clutch line change shifting was great. Now with the ACT clutch it won't quick shift at high RPM. UNder normal driving it goes in fine although it seems like the shifts are more notchy now. I'll compare the clutch pedal with the foot rest today. Did I adjusted clutch rod too far?

NOt sure if it's the clutch installment or my tranny is messed up. Seems to be a common crap on 03 EVOs.
