I had to wait for my son to show up for an answer to your problem, as I know very little about automatic transmissions. Marty said that there is a pin that sticks out of the actuator that fits a slot in the manual valve that you probably didn't get lined up with. If the tranny was working before, he said that is the only thing it can be.
Hope this helps and sorry it took so long!
