Condition

Difficult

Causes
Jor
difficu
t

gear

are
classi

fied
to
troubles

concerning
control

system

and
transniissioo
When

lever
is

heavy
and
it
is
difficult
to
shift

gears
clutch

may
also
be
unsmooth
First

make

correctly

and

Gear

In
most
cases
this
trouble
occurs
when

interlock

all
check
ball
and

or
spring
is

worn
or
weakened
or

when
control

system

is

faulty
In
this
case
the

trouble
cannot
be

corrected

by
replacing
gears
and
therefore

trouble

shooting
must
be

carried
out

care

fully
It
should
also
be

noted
that

gear
slips

out

of
mesh
due
to
vibration

generated
by

weakened
fron

and
rear

engine
mounts

Noise

When

ceases
when

it
is

shift

valve
FSV

The

FSV
is
a

transfer
valve
which

shifts

gears
from

low
to

When

Ihe
vehicle
is

stopped
the

FSV
is

depressed
to

the

right
side

by
force
of

a

spring
located
on
the

left
side

putting
the

FSV
is
in
the

low

position

When
vehicle

speed
increases
the

governor

pressure
15
is

applied
to

Ihe

of

the

When
the

exceeds
a

certain

the

governor
pressure

15
exceeds
the

and
Ihe

When

only
the

depresses

the

As

With

Howeve
f

the

nless
the

shift
valve
SSV

The

SSV
is

a
transfer
valve

which

shifts

gears
from

2nd
to

3rd

When
the
vehicle
is

stopped
the
SSV

is

forced
toward

the

right
by
the

spring
and
is
in
the

2nd

position
It

is

so

design
d
however

that
the
FSV

can

decide
to
shift

either
to

Low
or

2nd

When

the
vehicle

is

running
the

governor
pressure
15
is

applied
to

the
right
end
surface

and
th
SSV
is

forced

toward
the
left

Contrarily
the

Spri
l

line

pressure

and

throttle

press

force
the

SSV

toward
the

right

When
vehicle

speed
exceeds
a
cee

tain

level
the

governor

pressure
sur

passes
the
sum
of
the

spring
force
line

pressure
and
throttle

pressure
and
the

valve
is
forced
toward

the
left
The

line

pressure
3
is

then
closed
Con

sequently
the
forces

being
rapjdly

unbalanced
the
force

depressing
the

SSV
toward
the

right
decreases
and

thus
the
SSV
is

depressed
to

the
l

ft

end
for
a
moment

With
Ihe

SSV

depressed
toward
the

left
end
lhe

line

pressure
3

is
connected
with

the
line

pressure
10

the
band
servo
is
re

leased
the
front

clutch
is

engaged
and

AT
8
speed
is
shifted
to

3rd

When
the

accelerator

pedJI
is

de

prcssed
both
the

line

pressure
3
and

the

throttle

pressure
19

are

high
allll

the

SSV
is
thus

retained
in
nd

unless
the

governor

pressure
15

ex

ceeds
the

line

pressure
3
and

the

throttle

pressure
19

In
the

3rd

position
force

de

pressing
ihe
SSV

toward
the

right
is

retained

only

by
the

throttle

pressure

16
and

the
throttle

pressure
16

is

slightly
Idwer

than
that
toward
the

right
which
is

applied
while

shifting

from
2nd
to

3rd

Consequently
the

SSV
is
returned

to
the

2nd

position
at
a

slightly

lower

speed

Shifting
from
3rd
to

2nd

occurs
at
a

speed
slightly
lower

than
that

for
2nd
to
3rd

shifting

When
kicked
down
at
3rd

line

pressure
13
is

led
from
the
SDV
and

the

SSV
is
forced

toward
the

right

Although
the

governor
pres
ure
is

con

siderably
high
the
valve
is
forced

completely
loward
the

right
and
tht

SSV
is

thus
returned
to
2nd

When

the

shifted
to

2

or

range
at
the

speed

the
line

pressure
3
if
diained

at
the

MNV

Consequently
the

front
clutch

and
band
servo

releasing
oils

are

drained
As
a
result

the
transmission
is

shifted
to
2nd
or
low

speed
ai

though
the

SSV
is
in

the
3rd

posi

velocity
from

to

the
line

pressure
10
and
reduces

the

shock

the

shifting

Contrarily
when
the
lever
is
shifted

to
2

range
and
the

speed
is

shifted
from
3rd
to
the
2nd
the

orifice

depressed
the

the
