Been doing some studying at work (when I should be working LOL) on the Ultramatic service manual. It doesn't really explain how it works, but now my theory is that the piston that is sticking up is for activating the reverse band. I put the car in Reverse to remove the control valve assembly easier. Even though the fluid was drained, what is left in the body must have been enough to shoot the piston out. So I am guessing that it is normal.

My next step will be to disassemble the control valve and give it a good cleaning. Hopefully that will fix some of my issues.

Is there anything else I can take out of the transmission at this point for cleaning/inspection? Isn't there a governor somewhere?
