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

etc
In

these
cases
the

transmission
must
be

replaced

To

proceeds
as
follows

Place
the

by

sampling
the

leaked
oil
examine

whe

it
is

not

The

torque

like

Cleanly
wipe
off

dust
and
detect

the

spot
of

Use
nonflammable

ing

Raise
the

oil

temperature
by

op

erating
the

engine

shift
the

will

by
