Crystal Ball is kinda murky.

There is no such thing as Dextron 111. However, there is Dexron III.

What log splitter is it, what brand, engine, splitting forces, two-stage Barnes pump, etc.

For the average backyard wood splitter I always recommend Schaeffer's #254 in ISO 46 or 68.

Schaeffer's #254 Hydraulic Oil

ISO 32 is 10W,ISO 46 is 20W,ISO 68 is 30W,ISO 100 is 40W.How badly does it leak? DEX3 is like a multi weight favoring the thinner side.
 
According to Schaffer's TD-254 data sheet, Page 3 at

http://www.schaefferoil.com/254-supreme-hydraulic-oil.html,

their 100C viscosity for their #254 ISO 46 Hydraulic fluid is 6.7-7.3 cSt.

A Dexron III has a 7.3 cSt viscosity @100C.

The major difference between DexronIII ATFs and dedicated hydraulic fluids is the makeup of the base oils and PI package.

Dedicated hydraulic fluids such as Schaeffer's have better AW components, better emulsibility for moisture, and the correct friction modification.
