Here's a little trick i used many times to remove the pilot bearing.
Once the tranny is out look into where the pilot bearing is. Fill the
center of the bearing with grease. Now find a long rod, the same
diameter as the hole in the center of the bearing. Place it over the
hole filled with grease and give it a wack with the hammer. The
hydraulic pressure is more than enough to move the bearing out.
Sometimes it takes a second filling of grease but not to often.
