Trans Tune for moisture in hydraulic fluid [SOLVED]

I’d change the fluid but use Trans Tune as a pre-flush. Here’s what I’d do: add Trans Tune to the fluid, and run the equipment for 25-30 minutes. Change the fluid and add Trans Tune to the new fluid. Add 1 ounce of Trans Tune per quart of hydraulic oil. Keep an eye on the fluid as time progresses.
