Do you have the end cover bolted on? Torque all the bolts as per FSM. Leave the big sealing bolt out that covers the snap ring. Grab the tranny, flip it over and bang it gently on a thick piece of wood. The shaft will drop and the snap ring will grab the groove on the bearing. You will hear a click as it grabs. Flip trans over and confirm snap ring is seated on bearing groove. Torque large sealing bolt down and good to go. hth :smile:
