the performance level (Heavy Duty or
Street). Remove burrs and clean the
separator plate after drilling holes.
STEP 9. Install Aluminum Plug in
Separator plate (See Fig. 6). With Plug
installed in hole, hold Separator plate
parallel to anvil and strike plug squarely
with a hammer. Peen plug just enough
so it is snug in the hole and will not
fall out easily.
Reassembly
STEP 10. Place check balls in valve
body and case (See Fig. 12) in the
positions shown. Use a dab of
petroleum jelly to hold check balls in
position. Double check the checkball
placement against the provided
diagram to prevent misplacement.
Improper checkball placement can
result in severe transmission damage.
STEP 11. Snap new solenoid filters
into separator plate (See Fig. 5). Make
sure filters are on the correct side of
separator plate, Place each new
separator plate gasket on the
separator plate and check to make
sure no holes in the separator plate
are covered by the gasket. Use
petroleum jelly to stick gaskets to
separator plate during installation. The
gasket with the ‘C’ cut in it goes next
to the case and the gasket with the
‘V’ cut in it goes next to the valve body
(See Fig. 11). If your gaskets become
damaged anytime during the
installation of the kit, replace them. If
you can-not obtain B&M replacement
gaskets then purchase OEM gaskets
for your specific year and model
vehicle.
STEP 12. Heavy Duty Level Only; (See
Figures 7 or 9) Place the 3-4
Accumulator Pin in the case. Over the
pin place the Spacer, 3-4 Accumulator
Piston and Stock Spring (spring is
installed at step 14). Remove the
spring and piston from the 1-2
Accumulator Housing. Over the pin
Install the spacer, piston (notice orientation) and spring. Use
petroleum jelly to hold components in
place. Proceed to step 14.
STEP 13. Street Level Only; (See
Figures 8 or 10) Place the 3-4
Accumulator Pin in the case. Over the
pin place the spacer and 3-4
Accumulator Piston, using petroleum
jelly to hold them in place. Remove
the spring and piston from the 1-2
Accumulator Housing. Install both
spacers over the pin, then the piston
(notice orientation). No 1-2 or 3-4
accumulator springs are used for
Street level shift performance.
STEP 14. Make sure the 2-4 Band
Anchor has not fallen out (See Fig.
