CONTROL
VALVE

The

control
valve

assembly
consists

of

many
preci
ion

parts
and

requir
s

extreme

care
when
it
has
to

be
reo

moved
and
serviced
It

is

good
practice

to

place
parts
in

a

part
rack
so
that

they
can
be

reassembled
in

valve

body

in

their

proper
positions
Added
care

should
also
be

exercised
to

prevent

springs
and
other
small

parts
from

being
scattered
and
lo
t

Before

assembly

dip
all

parts
in

clean
automatic
transmission

fluid
and

check
to
be
certain

that

they
are
free

of

lint
and
other
minute

particles
If

clutch
or
band
is

burnt
or
if
oil

becomes
fouled
the
control

valve
as

sembly
should

be

ssembled

Notes

a
In
