I
is

led
to

the

reverse
clutch
from
the

line

pressure
5

through
the
line

pressure
12
and
at
the
same
time

the
same
is
led
to
the
left
end

spring

unit

Consequently
although
the

go

vernor

pressure
increases
the
valve
is

still

depressed
toward
the

right
and

the
SFV
is

fixed
in
the
Low

posi

tion
When

kicked
down

at
the

2nd

speed
the
SDV

operates
and
the

line

pressure
13
depresse
the
FSV
to

ward
the

right

Although
the

governor

pressure
15
is

considerably
high
the

valve
is

depressed
completely
toward

the

right
and
the

FSV
is

returned
to

the
Low

position
This

operation
is

called
Kick
down

shift

2nd
3rd
shift
valve
SSV

The
SSV
is

a
transfer
vaIve
which

shifts

speed
from
2nd
to
3rd

When
the
vehicle
is

stopped
the

SSV
is

depressed
toward
the

right
by
the

spring
and
is
in

the
2nd

position
It

is

provided
however
that
the
FSV

decides
the

shifting
either

to
Low

or

2nd

When
the

vehicle
is

running
the

governor

pressure
15
is

applied
to

the

right
end
surface
and
the
SSV
is

depressed
toward
the

left

Contrarily

the

spring
force
line

pressure
3
and

throttle

pressure
19

depress
the

SSV

toward
the

right

When
the

vehicle

speed
exceeds
a

certain
level
the

governor

pressure

exceeds
the
sum
of
the

spring
force

line

pressure
and
throttle

pressure
the

valve
is

depressed
toward
the
left
and

the
line

pressure
3
is
closed
Conse

quently
the
forces

are
rapidly
un

balanced
the
force
to

depress
the
SSV

toward
the

right
reduces
and
thus
the

SSV
is

depressed
to
the
Ie
ft
end

for
a

moment

With
the
SSV

depressed
to

ward
the

left
end
the
line

pressure
3

is

connected
with
the
line

pressure

10
the

band
servo
is
released
the

front
clutch
is

engaged
and

speed
is

shifted

to
3rd

When

the
accelerator

pedal
is

de

pressed
both
the
line

pressure
3

and

the
throttle

pressure
19

are

high
and
AUTOMATIC
TRANSMISSION

therefore
the

SSV
is

retained
in

2nd
unless
ihe

governor
pressure

IS
exceeds

the
line

pressure
3
and

the

throttle

pressure
19

In

the
3rd

position
force
to

depress
the

SSV
toward
the

right
is

remained

only
on
the
throttle

pressure

16
and

the
throttle

pressure
16
is

slightly
lower
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
low

speed
side

Shifting
from
3rd
to

2nd

occurs
at

a
speed

slightly
lower

than
that
for

2nd
to
3rd

shifting

When
kicked
down
at
the
3rd

line

pressure
13
is
led
from
the
SDV

and
the
SSV
is

depressed
toward
the

right
Although
the

governor
pressure

is

considerably
high
the
valve
is

de

pressed
completely
toward
the

right

and
thus
the
SSV
is
returned
to

2nd

position
This

operation
is

called
Kick
down
shift

When
the
shift
lever
is
shifted

to

2
or
I

range
at
the

3rd

speed

the
line

pressure
3
is

drained
at

the

MNV

Consequently
the
front
clutch

operating
and
band
servo

releasing
oils

are
drained
As

the

res
lIt
the
trans

mission
is
shifted

to
the
2nd
or

low

speed
although
the

SSV
is
in

the
3rd

position

When
the

speed
is
shifted
to
the

3rd
a

one

way
orifice
24
on
the

top
of
the

SSV
relieves
oil

transmitting

velocity
from
the
line

pressure
3

to

the
line

pressure
10
and
reduces
a

shock

generated
from
the

shifting

Contrarily
when
shifted
from
3rd

to
2
or

range
and
the

speed
is

shifted
to
the
2nd

spring
of
the
orifice
24
is

depressed
the
throttle

becomes
ineffective
the

line

pressure

10
is

drained

quickly
and
thus

delay
in
the

speed
shifting
is

elimi

nated

Throttle

of
the

line

pressure
6

relieves
the
oil

transmitting
velocity

from
the

line

pressure
6
to
the

line

pressure
10
when

the
lever
is

shifted

to
the

R

range
and
relieves
drain

velocity
from
the
line

pressure
10
to

the
line

pressure
6

when

shifting

from
3rd
to

2nd
at

the
D

range
Thus
the
throttle
of
the
line

pressure
6
reduces

a
shock

generated

from
the

shifting

A

plug
in
the
SSV
left

end

readjust

the
throttle

pressure
16
which
varie

depending
on
the

engine
throttle
con

dition
to
a

throttle

pressure
19

suited
to
the

speed
change
control

Moreover
the

plug
is

a
valve
which

applies
line

pressure
13
in

lieu
of
the

throttle

pressure
to
the

SSV
and
the

FSV
when
kick

down
is

performed

When
the
throttle

pressure
16
is

applied
to
the
left
side
of
this

plug

and
the

plug
is

depressed
toward
the

right
a
slight

space
is
made
from
the

throttle

pressure
16
to

19
A
throt

tIe

pressure
19
which
is
lower

by
the

pressure
loss

equivalent
to
this

space
is

generated
the

pressure
loss
is
added
to

the

spring
force
and
thus

the

plug
is

depressed
back
from
the

right
to
the

left

When
this

pressure
19
increases

excessively
the

plug
is
further
de

pressed
toward
the
left

space
from

the

throttle

pressure
19
to
the
drain

circuit

13
increases
and
the
throttle

pressure
19
lowers
Thus
the

plug
is

balanced
and
the

throttle
