You need to make up a pressure gauge and take a reading before you do anything...The relief valve I believe is under the seat on the tranny somewhere BUT you MUST have a gauge BEFORE you mess with it!

You can get a 0-3000psi gauge from TSC or the SurplusCenter, a short hose, and a coupler that will plug into one of your FEL ports to get the reading. (see attached picture) Once you have the gauge made up I can help you further.
