I was messing with that about a year or so ago, but my idle switch was working properly. Looking at the manual, it appears that the switch rolls around the linkage varying the pressure on the "trigger". Examine the screws, they should be loose, and one should be in a long slot.
The stator solenoid is the same as the detent solenoid. It is mounted on the inside of the pump. During assembly, you lower the pump into position and thread the wire into the main housing to be hooked up later when working on the valve body etc. If your wire has broken off of the solenoid, the only access will be to remove the transmission and pull the pump off the front.
Maybe someone with more experience with chime in. Otherwise I will try and see what I can find tomorrow.
