CAUTION:
Do not
force
the valves or plugs
into

place
during
reassembly. If the valve body
bores,

valves
and plugs are
free
of
distortion
or burrs, the
valve body components should all slide
into
place
easily. In
addition,
do not
overtighten
the
transfer
plate
and valve body
screws
during
reassembly.

Overtightening
can
distort
the valve body
resulting

in valve sticking,
cross
leakage and
unsatisfactory

operation. Tighten valve body
screws
to recom­ mended
torque
only.

with transmission fluid.
(2) Insert rear clutch and rear servo check balls in
transfer plate (Fig. 100).
(3) Install filter screen in separator plate (Fig.

check balls are approximately 1/4 inch in diameter.
(7) Align and install assembled transfer and sepa­
rator plates on valve body. Install and tighten valve
body screws alternately in a diagnonal pattern to 4 N»m (35 in. lbs.) torque.
(8) Assemble converter clutch module and valves.
Then install assembly on valve body (Fig. 108).
(9) Assemble regulator valve line pressure plug,
sleeve, throttle plug and spring (Fig. 104). Insert as­
sembly in valve body and install end plate. Tighten

ing E-clip. (28) Lubricate shaft of manual lever with light
coat of petroleum jelly. This will help protect seal lip
when manual shaft seal is installed. (29) Verify that throttle lever is aligned with end
of kickdown valve stem and that manual lever arm
is engaged in manual valve (Fig. 109).

FRONT CLUTCH CLEANING AND INSPECTION Clean and inspect the front clutch components. Re­
place the clutch discs if warped, worn, scored, burned or charred, the lugs are damaged, or if the facing is
flaking off. Replace the steel plates if heavily scored,
warped, or broken. Be sure the driving lugs on the discs and plate are also in good condition. The lugs
must not be bent, cracked or damaged in any way.
Replace the piston springs and spring retainer if ei­
ther are distorted, warped or broken. Check the lug grooves in the clutch piston retainer.
The steel plates should slide freely in the slots. Re­
place the piston retainer if the grooves are worn or damaged. Also check action of the check ball in the
piston retainer. The ball must move freely and not stick.
Replace the retainer bushing if worn, scored, or
there is any doubt about bushing condition.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
