To exactly locate the place
of oil
leakage proceed
as
follows
Place the vehicle
in
a pit
and
by
sampling
the
leaked oil
determine
ifit
is
the torque
converter
oil The torque
converter
oil has
a
color like red wine
so
it is
easily distinguished from engine
oil
or
gear
oil
Wipe
off
the leaking
oil and dust
and detect the
spot of oil
leakage
Use
nonflammable
organic
solvent such
as
carbon tetrachloride for
wiping
Raise the oil temperature by
op
erating
the
engine
and shift
the
lever
to
D
to
increase
the oil
pressure
The spot of oil leakage
will then be
found
more
easily
Note
As oil
leakage
from the breath
er
does
not
take
place
except
when
running
at
high speed
it is
impos
sible
to
locate
this leakage
with
vehicle
stationary
CHECKING
ENGINE IDLING
REVOLUTION
The engine idling
revolution should
be
properly adjusted
If
the
engine
revolution
is too
low
the
engine
does
not
operate
smoothly
and if
too
high
a
strong shock
or
creep
develops
when
changing
over
from
N
to
D
or
R
CHECKING
AND
ADJUSTING
KICK DOWN SWITCH AND
DOWNSHIFT
SOLENOID
When
the kickdown
operation
is
not
made
properly
or
the
speed chang
ing point
is
too
high
check
the
kick
down switch
downshift solenoid and
wiring
between them When the
igni
tion
key
is
positioned
at
the I st
stage
and the accelerator
pedal
is
depressed
deeply
the switch contact
should
be
closed and the solenoid should click If
it
does
not
click
it
indicates
a
defect
Then check each
part
with the testing
instruments

INSPECTION
AND
ADJUSTMENT OF MANUAL
LINKAGE
The adjustment of manual linkage
is
equally important
as
Inspection
of
Oil Level for the automatic transmis
sion
Therefore
great
care
should be
exercised because incorrect
adjustment
will result in
the breakdown of
the
transmission
Inspection
Pull
the
selector
lever
toward
you
and
turn it
as
far
as
p
to
I
range
where clicks
will
be
felt by
the
hand
This is the detent of manual valve in
the valve
body
and indicates the
correct
position
of the lever
Inspect
whether the
pointer
of
selector dial corresponds
to
this point
and also whether the lever
comes
in
alignment
with the
stepping
of
posi
tion
plate
when it is
released
Adjustment
This
procedure
can
be
accomplish
ed
by referring to

INHIBITOR
SWITCH
The inhibitor switch lights the

Check whether
the
reverse
lamp
and the starter motor
operate
nonnal
ly
in these
ranges
If there is
any
trouble
first check the linkage If
no
fault
is
found
in
the linkage
check the
inhibitor
switch
Separate the manual lever from the
remote
control selector rod and
turn
the range
select lever
to
N
Note In the
position
N
the slot of
the manual shaft is vertical
Using
the
tester
check the
two
black
yellow
BY wires
from the
in
hibitor switch
in the ranges
N and
P and the two
red black
RB wires
in the range R
for continuity Turn
range
select lever in both directions
from each lever
set
position and check
each continuity
range
It is
normal if
the
electricity
is
on
while the lever is
within
an
angle
of about 30
on
both
sides from each lever
set
line How
ever
if
its continuity
range
is
obvious
ly
unequal
on
both sides
adjustment
is
required
If
any
malfunction is
found
un
screw
the fastening
nut
of the range
selector
lever
and
two fastening
bolts
of the switch
body
and then
remove
the machine
screw
under
the
switch
body
Adjust
the manual shaft

to
the
position
N
by means
of
the
selector lever
When the slot of the
shaft becomes vertical
the detent
works
to position
the shaft

a
clicking
sound
