For

Lack

of
oil
causes
defective

opera

tion

by
making
the
clutches
and

brakes

slip
developing
severe

wear

The

cause
of

this

operation
is
that

the

oil

pump
has

begun
to

suck
air

which

caused
oil

foaming
thus

rapidly

deteriora

ting
the
oil

quality
and

pro

ducing
sludge
and

varnish

Meanwhile
excessive
oil
is
also
bad

as
in
the

case
of

a
lack

of
oil
because

of
oil

foaming
by
being
stirred

up
by

the

gears
Moreover
in

driving
with
excessive
oil
in

Inspecting
oil
condition

The
condition
of
oil

sticking
to
the

level

gauge
indicates
whether
to
over

haul
and

repair
the
transmission

or

look

for
the

defective

part

If
the

oil
has
deteriorated
into

a

varnish
like

quality
it

causes
the
con

trol
valve
to

stick
The
blackened
oil

gives
the

proof
of
the
burned
clutch

brake
band

etc
In

these
cases
the

transmission
must
be

replaced

Notes

In
