B&M 40227 TRANSPAK - Manual (Page 7)

STEP 18. Check your parts before
proceeding, you should have (3) stock
springs and no check balls or relief
valves left over. Make sure the (12)
valve body plate bolts are properly
torqued.
STEP 19. Remove all old gasket ma-
terial from the case surface. Install (2)
M6x40mm (1.56") alignment pins
(supplied in kit) into the holes shown
(See Fig. 6). Install case to separator
plate gasket over alignment pins. Use
a few dabs of grease tho hold the
gasket against the case.
CAUTION: Valve body installation
is one of the most important steps
to insure proper operation of the
AOD transmission. The valve body
must be located flush against the
case and carefully torqued exactly
as described in the following step.
Failure to follow this procedure
can result in sticking valves and
unpredictable transmission opera-
tion. If the valve body is warped or
damaged due to improper assem-
bly it is not repairable and should
be replaced.
STEP 20. Install valve body up to
case being careful to align manual
valve with pin in detent plate (See
Fig. 7). You also have to manually
engage the TV lever between the
valve body and TV plunger. DO NOT
try to force the valve body into place,
it will go right into place with a little
patience. With the valve body sitting
flush against the case install (1) bolt
to hold the valve body in place. Make
sure the detent plate pin and internal
TV lever are properly positioned then
install (8) short M6x30mm (1.16") and
(16) M6x40mm (1.56") shoulder bolts
(See Fig. 1). Remove the alignment
pins only after all but the last two bolts
have been installed. Install ALL bolts
FINGER TIGHT. The short bolts are
installed (4) in front (1) in center and
(3) in rear of valve body. One of the
shoulder bolts holds the detent lever
spring. Starting at the center and work-
ing outward torque bolts to 80-100
lb.in. (9-11 Nm). If you do not have a
low range torque wrench, run the bolts
down until they stop (wrist tight) then
turn bolt an additional one eighth (1/8)
turn.
STEP 21. Position the TV torsion
spring against the separator plate ‘V’
