Did all switch pitch transmissions have the two prong connection on drivers side?
yes. One for the switch pitch, one for the kick down.
Yes. (and no).
The switch requires two wires for the hi-lo positioning of the stators and kick down.
I have an ST400 from a '67 Electra that has no horseshoe, only two dimples and a single blade, but the pump and TC were Switch Pitch parts.
Pulled the pan and the wires are there.
So, either it may have been at a time that Buick started "un-switch pitching" and it left the factory working as a typical ST400, or it was a rebuilt and they disabled the function by changing the switch to only run the kick down.
But why the pan is like an ST400, I am not sure.
Anyway, Jim Weise has it and is teaching it to be it's younger self again.
I would think you would have to have 2 plug......1 kickdown, 1 for solenoid for the switching. But not all transactions with 2 plugs are switch pitch, seen some have a smog switch for some reason not sure what it did, but was a later 70's or early 80s trans
