CONTROL
VALVE

extreme

good
practice

to

place
parts
in

a

so
that

they
can
be

reassembled
in

in

Added
care

should
also
be

exercised
to

prevent

springs

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

is

burnt
or
if

the
