If you had the valve body out of the transmission, then as you put it back in, there is a valve that has to line up properely with the linkage that passes through the case for the linkage outside the transmission. They call the valve in the transmission the manual valve because it has to be moved manually to select what gear you have.
Been tooooo long since I have looked in the powerglide, but that valve may have two grooves close to one end that has to straddle the linkage that comes through the case. (Someone correct me if I'm wrong). If it is not in place you can't select what gear you want. Some transmissions use an "s" shaped link to connect the two.
I'll see if I can find a picture today and post it later to give you a better idea of what to look at.
