I don't know what that would tell you. I mean, if there was no fluid coming out, that'd be one thing - but then your car wouldn't be working, either.
You need to hook a pressure gauge up to one of the test ports to get any useful info.
I don't think you have a pressure problem. If you did, your transmission would be slipping and burning up the fluid and its clutches...and you'd see higher temperatures, I'd wager.
