Switch looks like this

INPA shows all the switch inputs as being correct, and I also checked them with a multimeter.

I have the transmission out now, will open it up in the morning. However my big concern is the solenoid actuation on two different EGS controller differs from the charts I can find. Solenoid 1 actuated in Reverse instead of solenoid 2.
