Hi, Looking for a bit more help on the Sportwagon restoration -This time related to the ST300 and the switch pitch system
1 - Can anyone tell me just how the two-wire outer connection at the transmission comes off? I know this may seem obvious but mine seems really tight or stiff and I have tried easily prying the black plug connector off of the trans plug(solenoid switch?). I cannot seem to loosen it or get it off. The plastic plug (solenoid switch?) in the trans is now moving, and now is leaking fluid...from my "work". I see in the chassis manual on this website fig. 5-107 how the solenoid sits in the trans body - it probably has an oring or two that are now leaking? But how does the outside connector come off ? - is it locked in any way or should I just keep pulling / prying straight off?
I have the stator and detent switch off at the engine end (intake off for painting/gaskets) - and want to remove the assembly but cannot seem to disconnect at trans connector...
2- Does anyone have a photo or better diagram than that on fig 5-38 of how exactly the idle stator microswitch at the throttle linkage is activated? Is there a lever or rod or screw that touches it? I feel someone may have removed a part(s?) off of my engine. Everything looks right however no apparent means of depressing the micro switch.
I have attached photos from my car
Thank-you in advance
