/ Modern Fluids in Old Tractors? #21

I was just wondering about use in my hydraulic system. Right now that’s a Cessna hydraulic pump (yes, MF bought that pump) and a Davis FEL, so pump, control valves, cylinders, no clutch pack or torque converter. The original manual says Type-A ATF, but my thought is that any of today’s ATF should be fine as hydraulic fluid, and the friction modifier issue is moot. Right?You may want to use Type F fluid because Dextron has friction modifiers in it that isn't good for clutch packs. Friction modifiers = slipping. F will provide crisp shift. Slip means wear.
