The trans assy has to see proper TV pressure to operate properly according to its' calibration(s). You would/could fine tune and modify from that point. The same with a vacuum modulator valve, it is adjustable.
Or am I off on an incorrect tangent?

You are correct on everything but minimum pressure. Minimum pressure is when the TV valve is extended fully against it stop. With the linkage at rest or removed the valve will be against its stop due to spring pressure. The stop is not adjustable so minimum pressure is not adjustable. Then when the throttle is applied the rod and lever moves the valve in increasing the TV pressure, This pressure is adjustable by lengthening or shortening the rod.
The original posters problem was the shift points are too high and too firm which is caused by TV pressure being too high at minimum throttle. With the rod disconnected something is keeping the valve from extending far enough to lower the pressure enough for a proper shift speed and feel. Either a binding lever or a bent TV valve stop. The binding lever can be detected by feel, spring pressure one way and a solid stop the other.
I 'm thinking the L shaped stop bracket is bent in increasing minimum pressure.
