Clutch chatter.
ahhh yes. i too have had (and occasionally still do) have the bad chatter in
first and second.
what I was told (by folks at a British car repair shop)....
it is the pressure plate that is the culprit.
why?
i was told that the plate was either not torqued down properly and
evenly...or
over time has lossened a tiny tiny bit. In order to solve the problem, I
decided
to replace the entire clutch before a long new england road trip vacation. I
did
not want any chatter or any problems.
when i installed the new plate, i torqued it correctly and evenly. (snug all
bolts with the fingers, then go back and work in a star pattern to increase
the torque to each bolt.)
This seemed to fix the problem. ... until many miles and years later (aka:
now)
it seems to be back slightly.
whether that was actually the real problem, i do not know for sure.
a pain to get in there to test the theory.
good luck, and post any other theories or solutions to this problem.
because mine might be wrong.
cheers.
