A question for GM Line Rat

Hey, I have one question to ask. The first to second shift solenoid you stated in thread:

http://www.automotiveforums.com/vbulletin/showthread.php?t=909526

is that the two electronic devices that mount on the valve body, or is that the plunger assembly that is inside of the cylindrical part of the casting? Items 10-21 on the bottom photo are what I'm refering to.

Thanks.
