I've been pretty clear in my posts about what tractors I was refering to. 
The ford 9n, 2n, and 8n. 1939-1952

Starting with the NAA in 1953, the hydro pump was moved out of the center 
section and became engine mounted, and thus live.. and used a thinner 
hydraulic or utf type oil.  This did away with the single sump, and there 
was now a sealed tranny sump, diffy sump, and hydro sump.  Gear oil for the 
diffy, and gear oil or utf for the tranny sump. and hydro oil or utf oil for 
the hydro sump.  Ford SOS units had to use the thinner oil in the 
transmission.. etc.
