TRANSAXLE
NOISE
Noise
characteristics
in
the
transaxle
are
more
difficult
to
diagnose
and
repair
than
me-
chanicalfailures.
Some
transaxle
noise
heard
only
at
certain
speeds
or
under
remote
condi-
tions
must
be
considered
normal.
Transaxle
noise
tends
to
be
more
pronounced
in
certain
gears
when
the
variable
speed
control
lever
is
forward
(fast
speed
position).
This
noise
is
NOT
:1
sign
of
trouble
in
the
transaxle.
Abnormal
gear
noise
can
be
recognized
since
it
produces
a
"clicking"
sound
and
will
be
very
pronounced
in
the
gear
range
in
which
the
noise
occurs.
If
damaged
gears
are
in
the
differenti:::ll
components
of
the
trans
axle,
the
gear
noise
will
be
pronounced
in
all
gear
speeds.
Gear
chatter
and
noise
has
been
found
to
be
a
two
cluster
gear

assembled
in

position.
This
occurs
on
certain
origi-
nal
4-speed
transaxles
when
the
transaxle
has
been
disassembled
and
transaxle
noise
persists.
Check
for
improper
assembly

cluster
gear.
Chronic
complaints
of
transaxle
noise
when
there
is
no
conceiveable
cause,
can
be
minimized
by
adding
a
commercial
gear
supplement,
such
as
"Slip

to
reduce
normal

ar

level.
