I'm about to service this system in my 4000 express, year 2000. A decal on the DYNA JACK unit indicates " Use Dextron automatic transmission fluid only. The use of other fluids may cause the unit to fail. Fill the tank to within 1/2" from the top with cylinders collapsed".
The reservoir tank is about 490 cubic inches which equities to about 8.5 quarts of ATF. The current filter is a Zinga BE-10-18 (10 micron), I'll be using a Donaldson P550426.
