of the transmission and remove the twelve capscrews
and lockwashers securing the transmission to the
engine flywheel housing.
3. Remove the transmission and place it in a clean work
area where the torque converter can be removed. It is
recommended that the transmission be mounted in a
service fixture.

flywheel through a drive plate. Remove the drive plate
mounting screws and remove the torque converter and
drive plate.
