Hi Jamey,
I don't know Delco 400 heavy duty, but if it says "for diesel engines" on
the container, you are ok.
SAE 90 or 80/90 gear oil is fine .
ATF for the hydraulics is a NO/NO. ATF can not be used for anything on the
Porsche-Diesel tractors, incl. the fluid coupling. Quickly change it to
Hydraulic Oil or SAE 10 motor oil.. Valvoline make a nice hydraulic oil and
you can get it at NAPA or any good automotive store.
Roland
