Anyone have any ideas about this one??? I get a knocking noise from
under the car when the clutch pedal is let out. This happens whether I
have the car in gear or in neutral. When I depress the clutch pedal the
noise slows quickly and then stops. The speed of the knock follows the
engine RPMs, so higher RPMs equals more knocks per second.

When the transmission is in neutral and the car isn't moving are any
parts turning inside of it?? I ask because I'm trying to guess whether
it is the throughout bearing or a bearing in the transmission case going
out.

Thanks,
Keith

Yes in gear or not, moving or not, the input shaft and the lower countergear
are turning when the clutch is "out". What you describe is an internal
transmission problem, not a clutch issue. Sorry...

Thanks Steve that was what I was afraid of. Do you have any idea of how
expensive a repair it would be?? I'm trying to decide whether to have
this on repaired (175,000 miles on it) or just buy a remanufactured one.

Thanks,

Keith

Get a second hand one from a wreck.

I'd put a used one in. This isn't a comon problem and a car that old isn't
likely to wear out another one.. I wouldn't have one that is -that- noisy
repaired, probably has damaged gears which is very expencive.
