For 
instance
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
high 
speed
driving 
with 
excessive 
oil 
in 
the 
trans
mission 
the 
oil
often 
blows 
out 
from
the 
breather
I
Measuring

ture 
50

800e 
122

Approximately 
ten 
minute
operation
will 
elevate 
the
temperature 
to 
this
range 
and
enigne 
idling 
conditions
are 
stabilized 
Then
apply 
the

and 
move 
the 
transmission

through 
all 
drive
positions 
and
place
the 
lever 
in

P
position 
In 
this
inspection 
the 
car 
must 
be
placed 
on 
a
level 
surface
The 
amount 
of 
the 
oil
varies 
with
the
temperature 
As 
a 
rule 
the 
oil
level
must 
be
measured 
after 
its
tempera
ture 
becomes
sufficiently 
high
I 
Fill 
the 
oil

the

therefore 
take

2 
At 
the 
time 
of 
the
above
topping 
up 
and
changing 
of 
oil 
care
should 
be 
taken 
of 
to
prevent 
mixing
the 
oil 
with 
dust 
and
water

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 
a 
In

use
special
paper
