No
Some times yes, other times no.
yes the transmission and rear end are open to each other, use- transmission hydraulic oil-
fluid and hydraulic oil the same thing
There are several designs but they all do the same thing, cool heated oil be it engine oil, transmission oil, hydraulic oil, etc.
Hydraulic fluid and hydraulic oil are one in the same.
The Ford 134 oil is a Hydraulic/Transmission Oil these appear to answer your question. See the provided links I would however recommend AMSOIL's SYNTHETIC TRACTOR HYDRAULIC/TRANSMISSION OIL ISO 46, SAE 30 See provided link.
It would eventually take a toll on the transmission. ATF and hydraulic oil have different compositions, detergents, and viscosity ratings.
Mobil 424 hydraulic transmission tractor oil or Amsoil tractor hydraulic transmission oil
They are different, auto trans use hydraulic oil or ATF ( automatic transmission fluid ) and manuals use that or a very thick version of gear lube like 80w-90.
hydraulic oil,AW-300
I suppose that TCH is Transmission Converter Hydraulic.
