"Well... maybe it has a little something to do with this.. maybe.?"

I wasn't asking about what caused it, I was asking about what the problem is

Anyways, the clutch was misbehaving before I did that.

If you want some good advice you need to offer as much information as possible and not discount other pertinent info that you describe in one post and then leave out in this post. If you give half-*** information you usually get half-*** advice.

The problem here were you jumping the gun an assuming that what I wrote in a previous post caused this problem.

How come that is my fault?

My clutch is feeling wierd exactly like I described, and I first noticed it on trip to work when I shifted at 4k rpm. I drive my car slow and nice.

Dude, all I'm saying is that something you mentioned in a previous post could help explain some of your current issues. Droping into 2nd from 75mph will take it above redline with no protection. Given this information, other folks with rotary and tranny experience may be able to ask additional questions about your problem. I don't think we have mind readers on this forum, you need to explain as much as possible if you want somebody to help you.

maybe you two should arm wrestle???? but watch out brother voodoo- if he has an arm strong enough to shift into second at 75 mph- he is gonna have one hell of a arm wrestler weapon there!

Crap, all I wanted was to figure out what was wrong with my clutch, and I end up in a bar brawl. I was kinda hoping that my rotten personality wouldn’t give me away when I was typing at a message board, but I guess I was wrong.

Could possibly be. Guess I'll have the service rep look at it when I take it in for my 3k oil change.

Now all I have to figure out is how to get rid of the rattling sound inside(!) my dashboard when I make left turns. This would make more sense if I was on drugs.

It could be a number of things related to the clutch as simple as the pressure plate coming loose, to something more serious such as a bad pilot bearing or a blown disc. It is kinda hard to diagnose over the internet.

Ok ill try anything.... Well ok 3 days down the road I have my gas light on with 210 miles dam it works( ha ha yeah right now I have like 15 mpgs).Well i am getting fed up i am going to go home and reset the ecu and then teach it to be driven at high rpms maybe that will help. Well till then I will keep you posted of the results.
Popping out of gear is definitely not a clutch problem so I am a bit suprised about changing the clutch. What ended up failing on the clutch? Thanks!

I prefer hydraulic clutches better then sping clutches.
What is a "sping" clutch? How is that different from hydraulic clutch? Actually the stock RX8 clutch is almost identical to the Turbo II clutch. A hydraulic system does tend to be more efficient and therefore easier on the foot.

What makes the release point consistent is the ability for the fluid to transfer from the master cylinder to the reservoir through a port that is open only when the master cylinder piston is all the way back. This is how the hydraulics self-adjust for wear. If the release point is changing the port is getting blocked at the M/C by either misadjustment of the pedal assembly or debris.

The coefficient of friction is always higher until the clutch is broken in. Higher friction will often produce chatter. Loose clutch bolts will also cause chatter, as will a damaged disc.

Clutch Noise

I got home today and parked my ride in the garage. I put her in neutral and to my surise when I let the clutch out I hear a new rattling sound. Has anyone else experienced this problem? When I push the clutch in the noise goes away. Do you think this will have damaged my transmission at all?


Thanks,
SPOOOOOOOOOON

I have always had a "whine" when letting the clutch out after starting the engine, but no knocking or mechanical sounding anomolies that I would consider unusual.

Did you hit something, mis-shift, or otherwise do something to 'harm' the drivetrain?

I did not do anything unusual to the car. I have been driving manual transmissions for over 20 years and this is the fisrt time I have ever heard this 'rattling' sound when I let the clutch out in neutral

Yeah, that seems logical. The clutch seemed ok when I first started driving the car, but now it is uneven and jagged. I guess I were an experienced driver and used to know what the clutch felt like. Guess I forgot it all.

I am having a similar problem with my car. When I let the clutch out in neutral I get a grinding noise. I never shifted from 6 --> 2 I just took it to the dealer today and the tech said he thinks it is the throw out bearing. Won't get my beloved car back until after the new year. For some reason he says he has to pull the transmission out

Just to set the record straight.

The clutch was behaving like this BEFORE I did the 6 -> 2.
AND How can the clutch be damaged when you do something like that? If anything were to blow up it would NOT be the clutch. AND I am positive that it is the clutch since this behaviour is present even when the car is in neutral.

I was only doing 75, and by the time I dropped the clutch in to 2 my speed was a little lower. But for the heck of it lets calc with 75mph.

So lets do the maths.

6 gear is 0.843, second gear is 2.269.

Divide second gear ratio with sixth gear ratio and you
end up with ~2.69.

At 75mph you have approx 3750rpms in 6 gear.

3750 * 2.69 = ~10093 rpms in 2nd gear.

If anyone has seen the best motoring vid you know that it can handle 10k rpms.

Ok again:
This was present BEFORE I did the 6->2.
And by doing the maths we proved that what I did could hardly
harm the car.

I think there is a bit of a difference between accelerating up to 10k rpms in second gear and dropping it in at 75mph. Dropping it into 2nd gear at 75 mph I think exerts more pressure on the cluth and transmission than if you had accelerated in 2nd to 75 mph. But wtf do I know. I bought the car cuz it looked sooooo coooooool. heh.
