It

CHECKING
OIL
LEVEL
In
checking
the
automatic
transmis
sion
the
o
illevel
and
the
condition
of
oil
around
the
oil
level
gauge
should
be
examined
This
is
an
easy
and
effective
trouble
shooting
procedure
since
some
changes
in
oil
condition
are
often
linked
with
developed
troubles
For
instance
Lack
of
oil
causes
faulty
operation
by
making
the
clutches
and
brakes
slip
resulting
in
severe
wear
This
is
because
the
oil
pump
sucks
air
causing
oil
foaming
thus
rapidly
deteriorating
the
oil
quality
and
pro
ducing
sludge
and
varnish
Excessive
oil
is
also
bad
because
of
oil
foaming
caused
by
the
gears
stirring
up
the
oil
During
high
speed
driving
excessive
oil
in
the
transmission
often
blows
out
from
the
breather

indicates
whether
to

look
for
the
