Probably won't hurt anything, but if it were mine I would want all the same fluid. Why take the chance on incompatibility problems hurting your pump?

ATF is commonly used as Hydraulic Fluid, but my manual also said don't mix them. Not sure why. If it did not foam or separate, I don't think I would worry about it.
I had a hard time finding Hydraulic Oil in less than 5 gal containers, until I found it at Home Depot. They carry it in one gal jugs.

atf has completely different anti-wear additives than hydraulic fluid. It can have similar viscosity but they are not the same.

Hi
I have a Caterpillar 950 loader.The site glass on the hydraulic tank has been sandblasted,making it cloudy.Every yr or so i add a pail of ATF to the AW 32 that i usually use in the hydraulics's.Makes the fluid pink and then i can see the fluid in the site glass.The AW 32 is clear.I have been doing this for the 15 yrs i have had the loader,it spends it's Winters working a logging show,and there have been no issues.
In the past we used 10W oil for hydralic's,then the AW 32 came down in price,so it's the goto fluid now.
