Never said there was the same pressure throughout the transmission. The maximum pressure in the transmission is determined by the capacity of the pump and the demand being put on it. A valve cannot increase that pressure, it can only reduce it.
Really? So if take a garden hose that you say has 100 psi pressure coming out of it and attach a nozzle(aka valve) on it that reduces the opening size then it will not increase output pressure? Isn't that not increasing the output pressure with a valve? So how can you say that a valve cannot increase output pressure going to the various systems of a transmission?
And before you start talking about flow again, please read the link I provided that how an automatic transmission pressure control solenoid/valve body works by decreasing flow to certain areas in order to increase it to others.
