Working with a Merc TRS here. On the trailer when the drive is in the full up trailering position it will stay there fine. However if you raise it to where the limit switch shuts it off and leave it it will slowly bleed down over say an hour. I have tried 3 different pump valve bodies (Prestolite pump) and finally bought a reman valve body and it still does it. Before messing with the pump I disassembled the cylinders and they appeared fine inside. Didn't replace anything in there though. Maybe I should have replaced the O-rings. Any ideas? I'm pretty much convinced it must be in the cylinders.
