Shift Shaft help

I don't remove the pan and valve body to remove the seal from the bottom by punching it out. I remove it from the top with a screwdriver. Removing the vb makes room for the screwdriver. Plus you can use sandpaper to clean up the shaft. You need to get an eyeball on that shaft to check it for wear. It might need replaced, or, if it's not too bad, you can use a taller seal.
