12 threaded holes for flexible plate attaching
screws in the flywheel.
NOTE
For more clearance between the tag axle and
transmission, the tag axle may be unloaded
and jacked up, or retracted (if applicable).
With the starter motor removed, align one of
the 12 attaching screw holes in the flexible
plate with the access opening.
3. Lubricate the flywheel center pilot boss with
molybdenum disulfide grease (Molycote G, or
equivalent).
4. Raise transmission and position the flywheel
pilot boss into the flexible plate adapter. Align
the guide bolt previously installed in the
flywheel with the flexible plate hole facing the
access opening in the flywheel housing.
WARNING
Severe damages and/or personal injury can
occur if transmission is not adequately
supported.
5. Seat the transmission against the engine
flywheel housing. NO FORCE IS
REQUIRED. If interference is encountered,
move the transmission away from engine,
then investigate the cause.
CAUTION
The torque converter housing must be seated
against the flywheel housing prior to tightening
any screws. DO NOT USE SCREWS TO
SEAT THE HOUSING.
6. Start all torque converter housing screws,
and then tighten four of them gradually and in
a criss-cross sequence around the housing.
Tighten the 12 remaining screws.
