'98 Honda Civic, Grinding Transmission
purchased a 98 Honda Civic DX after putting about 1000 miles on
it, now 57,000 miles, it has an occasional high pitched grinding noise
while accelerating. This is the best I can describe it. It occurs at low
speeds and goes away. Also, it does not happen every time I drive. Am
I right in thinking I should service the transmission? Or what should
I have checked?
suggest checking the transmission fluid level to be sure it is right,
but it is unlikely that a transmission fluid service is going to correct
a grinding noise. Your Honda is of the right age that I cant help
but wonder if what youre trying to describe, as a grinding noise
is really an exhaust shield that is rattling. The shielding, if failing,
on the exhaust of your Honda can rattle and vibrate at such a speed that
it sounds more like a metal type buzz or grind type noise. If this is
the case youll often find that you can make the noise happen as
the tachometer gets in the 2000 RPM range and is most noticeable when
accelerating. It is rarely heard at cruise speed or light throttle operation.
Before you start spending money guessing, or having needless service performed,
have the vehicle checked over. It might be as simple as an exhaust clamp
to rid your Honda of that noise.
