Bad valves in the pump, bad o-rings in the ram...
More info needed.

You can leave the atf in there as it will work fineSo far i've gone through the trim pump and all the check valves seemed ok for the most part. Little bit of corrosion on some of them but not the one that holds pressure in the rams.
the cylinders havent been opened probably since new so i have no idea what they look like inside.
Whats a good substitute for the 20w MS oil the manual calls for? I currently have it filled with dex/merc atf since thats all i had.
