Checking Line pressure on 727 transmission

What is involved in checking the "Line" pressure on a 727? Basicly i have a concern that it might be to high and causing a problem with my TQ converter. What are my options?

Thanks

Put a pressure gauge on the low-rev servo tap on the rear pass side of the case. U have to drop the pan to adjust the pressure. 3/16th allen on the side of the vb. turn clockwise to lower pressure. They say 1 turn is good for 10#.
