Going to belabor this issue just a little longer because there are a few fine points. Yes, HY-TRAN was developed for hydraulic and mechanical transmission of power, but both the hydraulics and gearing on the new machines were designed for this product. HY-TRAN does not have the film stability at high temperatures or high loading capability that gear oil features. John Deere standard Hy-Gard is a similar product to HY-TRAN but contains zinc antiwear compounds and has a slightly higher viscosity. Both features would improve film stability compared to HY-TRAN. But the zinc antiwear compounds are not always compatible with IH clutch/brake material and I never use anything but HY-TRAN in CIH machinery compartments that contain clutches/brakes. Interestingly many CIH dealers remove HY-TRAN from the older axial flow combine final drives and replace it with 85W90 or 75W90 gear oil to eliminate bearing problems. This supports the premise that gear oil gives more protection. I don't know what is specified for the new combine final drives, but I assume it is gear oil not HY-TRAN. You might have been lucky, or not have used the tractor in continuous high draft situations or Ford might have simply overdesigned the components and really didn't need the additional safety factor provided by gear oil. In a continuous high draft application such as plowing I probably wouldn't chance it, and if I did would use the John Deere product. One caveat, 75W90 gear oil might not adequate anti-foaming properties for use in high volume/flow hydraulic systems. I don't believe the early Fords will have this problem.
