NOTE: To put the splines on the transmission adapter in alignment with the flywheel, turn the
transmission oil pump shaft. To put the splines in the transmission in alignment with the splines
on the differential input shaft, the following procedure can be used:
a) Drain the oil from the tandem housings.
b) Remove the axles.
c) Turn the differential input shaft with a prybar or a screwdriver while the transmission is being
installed on the studs of the differential housing.
d) Install the axles and fill the tandem housings with oil to their correct levels.
3. Install bolts (2) that hold the transmission to the flywheel housing. Install the nuts that hold the
transmission to the differential housing. Connect oil lines (3) to their correct locations on the relief
control valve. Remove the hoist.
4. Put three control cables (7) in position on the valve links. Put couplings (6) in position in the
transmission housing. Tighten nuts (4) against the couplings. Put retainer (5) in position over the
couplings. Install the bolts that hold the retainer to the transmission housing.
