With the greatest of respect Harvey, your method of tampering with the wiring will never produce a result comparable to a proper TCU remap.

The TCU uses a very complex algorithm to determine the optimum line pressure to suit a whole variety of driving conditions. It is not simply proportional to the throttle position.

I am in full agreement with LAN here. The transmission is a relatively modern software-controlled system. The only correct way to recalibrate it is via remapping the TCU.

As Trevor cannot be here to defend what you call his bull$hit, I'm going to restate my conclusion that neither you nor Trevor have a complete understanding of how this system works.
