Unlike variable displacement pumps, gear pumps can't increase flow without increasing RPM.
How many times do I have to tell you that it is the pressure control valve/solenoid that controls(key word is controls there) the pressure to shift before you understand? Please show me what information you have that only the pump controls the line pressure on a modern electronically controlled transmission. Go ahead, I can wait......
Oh, and by the way, the pump on the 68RFE is a dual-stage pump with the primary always working and the secondary being bypassed when not needed.
