RANGE

In
N

range
none
of
the
clutches

and
band
are

applied
thus

no

power
is

transmitted
to
the

output
shaft

The

pressure
of

oil

discharged
from

the
oil

pump
is

regulated
by
the

pressure
regulator
valve

CD
to
maintain

the
line

pressure
7
and
the
oil
is
led

to
the
manual
valve

The
oil
is

further
introduced

into
the

torque
converter
at
its

op

erating
pressure
14
and
a

portion
of

this
oil
is
distributed

to
each

part
as

the
front
lubricant
The
oil
which
has

been

discharged
from

the

torque
con

verter
is
also
distributed

to
eacn

part

as
the
rear
lubricant

As

the
oil

pump
rotates
at
the
same

speed
as
the

engine
the
oil

pump

discharge
increases
with

engine
speed

But
the

surplus
oil

is
returned
to
