Then you need a pressure sensor and vacuum switch tee'd in a transmission's oil pressure port.

That is what i described in the drawing and functional description in post 1. Actually I think I'll use 2 vacuum switches, 1 for LU and 1 for OD. And possibly the B&M trans controller instead of the pressure switch.
