INSTALLATION
Transmission
1. CAUTION: During this move, to avoid damage, do not allow the transmission to get
into a nose- down position as this will cause the torque converter to move forward and
disengage from the pump gear. The converter housing is piloted into position by dowels
in the rear of the engine block. The torque converter must rest squarely against the
flexplate. This indicates that the converter pilot is not binding in the engine crankshaft.
Position and secure the transmission on the high- lift transmission jack.
2. CAUTION: Make sure the torque converter is fully seated in the transmission before
positioning the transmission to the engine.
Using the special tool, install the transmission to the engine.
zAlign the orange balancing marks on the converter stud and the flexplate bolt hole. 3. Reconnect the harness. SECTION 307-
