I’m afraid you’ve lost me. There’s hydraulic oil or transmission/hydraulic oil. They are not the same. It’s not of ANY importance to have an easy name, but of the UTMOST importance to ask for the correct oil for an hydraulic application or transmission/hydraulic application. Don’t lead equipment owners astray!!
What you need to ask for is an oil meeting a certain specification to make sure you get the right oil for your specific piece of equipment rather than just "transmission/hydraulic fluid." That specification usually is a manufacturer certification specification such as JD J20C but may also be an ISO/SAE viscosity grade (e.g. ISO 48) or fluid type (e.g. Type F automatic transmission fluid), or sometimes even a manufacturer's specific product (e.g. Mobil 1 15W-50.) Note that those examples are real, I have had or used equipment that have called for each of those types of fluids in a transmission/hydraulic setup. I've also used hydraulic setups that did not include a transmission that used those same fluids too (especially ATF.)
