I'm not yet sure exactly what is happening. I'll need to do some more driving to understand it. It could be that at some speeds it needs to do a double kick-down to get into the power band..... if so, maybe a cable adjustment will do the trick.

Adjusting the cable moves you up and down the pressure curve a bit but it does not change the slope of the curve that is needed to retune the transmission for the greater torque curve. That is where changing the control pressure valve comes in.
In the AW4 transmission behind the 3.5 the control pressure can be adjusted in some of the versions. The same transmission is used in Supra turbos and they can dial in different preloads on the valve. In ours we can either get the adjustable cap from a Toyota or make our own as needed.
