Hy-Tran is a superior oil to the TFD oil, better high pressure protection and has a seal conditioner as well as the ability to hold a certain amount of H20 in suspension, the current Ultra or super Ultra Hy-tran is a improved version of the original IH Hy-Tran at the time TFD was the best CASE had to offer in the high HP tractors, as for the posters ? on it he is correct in that CNH does not do the refining of the oil but they do hold the patent on the specific additives used in the OEM oil that bulk oil distributors can not supply as a exact replacement for CNH Hy-Tran, I along with many others here highly recommend using it, however if you have a oil that has been serving you well for many years without issues no problem as I have said before it is your equipment use what you like, when we are asked what we recommend we will say what we have found to be the best in our experience working on and running our and our customers equipment in the end it is always your choice

Case IH/New Holland does not refine or blend their own oil. The rights to Hytran are owned by Viscosity Oil Company who has contracts with blenders such as Warren Distribution and others to supply fluids blended to Case IH specs. Hytran is a premium product compared to TSC and other similar fluids.

Tom: Let me know if I"m wrong on this, but as I remember, the TFD (Transmission-Final Drive) was a heavier viscosity than the TCH (Transmission-Converters-Hydraulics) fluid. The TFD did not have the anti-foaming agents that the TCH oil has, which is why the TCH is recommended for Converters, Hyd"s & Power Shift Tranny"s. I don"t think TFD was ever recommended for the Power Shifts. TCH is still available, but TFD is not, so I"ve been told.

TFD was introduced to handle lube issues in the rears of 12-15's due to the increased power being transmitted through the gears in those tractors. It was eventually replaced by PTF.
After the merger CaseIH adopted HY-Tran and from there, CNH now has HT-Ultra. Time marches on!

John, "TCH" is still available although it costs more than Hy-Tran does as for "TFD" it was designed for 1270/1370 (1570 came later but used TFD as well) tractors that required a higher gear load oil so yes it was for power shift tractors, I was talking to Bro Loren when I opened this and he told me to tell you "it's back to the wood shed for you" LOL

Wood shed??!! Gotta catch me 1st!! I seem to remember the TFD being directed more toward the Construction side. I wonder if it was here in the East?

forgot to add "TFD" stands for T= transmission FD= final drives and as the 1270/1370 were the first CASE tractors to have internal final drives this should explain it being brought out at the time
