Twin disc transmission

Anyone familiar with twin disc transmissions? Both transmissions within hours of each other started to loose pressure when warmed up (20 mins). Whereas they both would run approx. 300 psi, now they will drop to 250 at cruise, 8 kts., and under200 at idle. I've cleaned the screens which were clean, changed trans oil, checked cooling system integrity. Ideas?
