I'm looking to service the transmission on my 1943 Case SC. I don't know if it's normal, but it growls when under load, in any gear. When coasting it's quiet. The fluid level is a couple inches below full and is black.
With that in mind, what round be the best choice of gear lube? The manual calls for 90W. I've seen all of the following recommended: 90w, 80w-90, and 85w-140.
