against case and remove the last bolt.
When removing valve body watch
out for about a pint of oil trapped
above it. Place the valve body on a
clean work surface. WARNING: Do
not place the valve body on the ground
or a dirty surface. The valve body
consists of precision fit valves and
will not tolerate dirt or burrs. Any dirt
entering the fluid circuits will jam the
shift valves and prevent the transmis-
sion from shifting.
VALVE BODY DISASSEMBLY
IMPORTANT: Pay special attention
in the following steps where some
steps refer to both Heavy Duty and
Street level modifications, while other
steps refer only to Heavy Duty or
Street level modifications. If neither
performance level is specifically re-
ferred to it means both Heavy Duty
and Street levels. It is a good idea to
retain all replaced parts (springs, etc.)
for reference until after the installa-
tion is complete and the vehicle is
satisfactorily road tested.
STEP 4. Remove 12 bolts holding
separator plate to valve body (See
Fig 3). Remove (3) reinforcement
plates and separator plate, (1) large
(orange) and (6) small (black) check
balls, and (2) relief valves with springs
(See Fig. 4). NOTE: Early 1980 valve
bodies may have (7) black check balls.
Carefully remove any remaining gas-
ket material from reinforcement plates
and valve body surfaces. Make sure
none of the gasket debris remains in
the valve body channels to contami- nate the valves. Rinse off valve body
with clean solvent to remove any dirt
or grit.
VALVE BODY MODIFICATIONS
IMPORTANT HINT: The retaining
clips at the end of the valve body
bores can fly off during removal. To
prevent losing the retaining clips place
a small rag over the clip when remov-
ing it, this will help prevent the clip
from flying off and becoming lost.
B&M does not stock replacement re-
taining clips. If yours are lost or dam-
aged see your local Ford parts sup-
plier or try a transmission shop.
STEP 5. Heavy Duty and Street;
Pressure regulator. Remove the re-
taining clip at the end of the pressure
regulator bore (See Fig. 4) Use a
Detent spring
guide bolt
