When I read this quote in the opening post:
"and then also from the torque we target a desired shift time. The shift time dictates amperage for the ratio change part of the shift.
We end up with a two stage pressure control for each shift. Much more refined and a lot more control of the more difficult shifts.", I took it to mean that the current thru the shift valve solenoids was being modulated to change the apply rate.
Thanks for the clarification; the feedback is much appreciated.
