Default Mystik JT-5 vs Case TCH

My Case 850B calls for TCH fluid in the transmission and hydraulic reservoir. The Case dealer is 100 miles away and wants a fortune for 5 gallons. Is JT5 a suitable substitute? If you believe what you read anything but TCH will result in a flaming catastrophic failure.

You are good with JT-5. The TCH fluid is a "lighter" duty fluid than the JT-5.

TCH fluid meets Case IH specification MAT-3506, it is an obscure spec.
that nobody formulates to except CIH. The JT-5 meets the more demanding
CIH specification MAT-3525.

The important issue with both fluids is that they will perform well in wet
clutches and wet brakes, both meet that requirement.

Where the specifications and fluids differ is viscosity TCH fluid is 40 cSt
@ 40°C and the JT-5 is 60 cSt. Now if you were Joey up in the great white
north during winter, that might be an issue. I don't think you have anything
to worry about in TN, but if it every gets below -20°F, (yes MINUS 20) don't
run your tractor with JT-5 in it.

Having an "oil" engineer on a forum where so many people are running machines and dealing with lubrication issues is pretty handy ain't it?

My Case skidder required 30 or 10 30 with a tch additive. I forget the name of the additive, but I still have several quarts if you want it. Should be back after the 4th.
