Is the 2nd generation clutch a so-called "wet clutch" or "dry clutch"? I assume it is a dry clutch as to my knowledge wet clutches are common only to motorcycles in current design.

There have been comments in various threads to the effect that there are additives available to reduce mild clutch chatter which commonly happens when a clutch is feathered in.

So my question is, how can an additive affect a "dry clutch" which I believe is what we are using in 2nd generation M/Ts? I assume a dry clutch means no oil is involved in the actual clutch interface. Am I wrong?

Additives??
Can you post any link(s)?
I've heard/read about people lubing the clutch (linkage) but thats it.

Automatics have "wet clutches" in them. The clutch is sitting in trans oil. A manual has a dry clutch that is outside of the transmission, no oil that is why it is a dry clutch. Additives can change the properties of the oil in an automatic and cause the plates to slip or improve the friction of the plates. You normaly do not get "chatter" from an automatic unless the trans is wore out.

Because you asked, I went back and looked for "good examples".

After re-reading, re-searching etc, I realized I was confusing differential additives for limited slip differentials, comments on wet-clutch addtives using google, comments on automatic transmissions etc.

So there are no additives for vehicle clutches, because they are dry-clutches, and any sense of chatter while feathering in a clutch may be because you are close close to end-of-life for your clutch. (is that right?)

Exceptions might be because you have a ceramic clutch which is generally considered a poor choice for non-racing vehicles.

A chatter when you have a rear-slip condition might benefit from a "friction-reducer".

So am I closer to getting it right? ....thanks Rocket.
