the pan to drop down. If the pan sticks
to the gasket, insert a flat screwdriver
between the pan and case and pry
down gently to break pan loose. Now
slowly back the bolts out to permit
draining the remaining oil. Remove
all old pan gasket material from the
pan and case.
STEP 2. Remove three (3) screws
holding the oil filter then pull the filter
straight down from the valve body.
Remove the filter grommet and gas-
ket material from valve body. (See
Figs. 1 & 2.)
STEP 3. Remove all of the valve
body bolts except one near the center
(See Fig. 1). Hold valve body up
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 (separator
plate, springs, etc.) for reference until
after the installation 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.
