80/90 gear oil or walmart tdh hydraulic fluid?

We usually use hyd. Oil in the trans. Do to the fact in cold weather it's harder to pass 80/90 threw system. Unless your tractor leaks a lot of oil. I would recommend the hyd. Oil.

wow.. your tractor really reccomends a straight hyd oil in the trans and not a utf?
