TCH Fluid

[RD Tx]

Does anyone have a cross reference on TCH fluid? The closest CASE dealer is 40 miles from here. Is this a standard brake fluid or something special.

Thanks,

TCH (Torque Convertor Hydraulics) is basically the same as all trans-hydraulic fluids. AutoZone in your area? They carry the equivalent fluid in 5 gallon buckets. It says right in the fine print that it's compatible. A trans-hydraulic fluid has a few more lubricating properties than regular hydraulic fluid.

Be sure to put in the better fluid, The hydralic grade is just for hydralics, the next grade is for transmission/hydralic. I"m using the better grade as its comparable to Hy-Tran plus in my Case. My 2 cents..........

In general all the brand names manufacture an oil that they clain is compatible with the TCH oil. In our part of Penna. there was a company selling a product named Drydene which was touted to be comparible to TCH. Many Backhoe customers bought because of price considerations. A chemical in that oil swelled the piston packings to the point that the cylinder could not be disassembled except by blowing the rod and piston assy out hydraulically or useing the winch on our rollbacks to pull them apart. The loader cylinders would screech as they extended from tight packing. I am not stating that all oils but TCH will cause this problem but Drydene said their oil met Case specs. As we cautioned our customers not to use their product we were threatened with lawsuit, but none ever happened!!

Trans-hydraulic fluid is meant for transmission/hydraulic usage. There is NO need to use that in a backhoe hydraulic system. Use a straight grade hydraulic fluid. There are no moving parts that need the extra lubrication (transmission gears) of a trans-hydraulic fluid.
