ECU tune Transmission control unit?

Mine hates to be above about 185 and will cool off very quickly if it is much higher than 195, even with the stock cooler. This new transmission really gets after circulating the fluid, the pressure on the cooler circuit has nearly doubled at idle from stock. Perhaps I'll see it if I get stuck in traffic later this summer when it's over 100 outside.

Question:
Pressure on the cooler circuit; the stock cooler is considered restrictive. If it is bypassed, say into an auxiliary fluid to air heat exchanger that is less restrictive, the flow will increase and the pressure will drop. What effect (if any) would this have on system pressure to the rest of transmission?
