Important Note:
Only the specified sealant can be used. The
machine
MUST NOT
be operated for at least 6 hours after
sealant has been applied and the converter housing
assembled. This is to allow time for the sealant to cure.

Make sure that the front case and torque converter
housing (

undamaged. Apply a 3 mm wide bead of Bondloc B574
sealant to the front casing as shown at

shown for clarity). Make sure that sealant is applied
between all the port channels as shown. Take extra
special care in the area

as sealing is critical in these
areas. Be sure not to block galleries with sealant. Fit a
new ‘O’ ring
