I was having trouble with my 3-point not lifting, drained cleaned filter(dirty,and appeared to have some water in the fluid. filled with tractor supply universal hydro/tran fluid 10-30. not any better . so put it on back burner and just checked manuel today and it calls for 80 weight gear oil , must not be a mistake as I found it two places in the manuel. If this is right it should fix it if I use the 80 weight ,right?
