Toyota systems aren't picky about fluid. FWIW, I've used M1 ATF in my parent's Sienna and despite the fact these and the Canadian-built Lexus RX have a tendency to spring a leak from the passenger's side rack bushing seal, the rack innards were clean. LV "universal" ATFs have become my PSF of choice for systems that use ATF.
If it was a car calling for a specific fluid(German cars calling for Pentosin/Mercedes ZH-M fluid, GM/Chrysler calling for PSF and any electrohydraulic system calling for OEM-specific fluid), stick to that. I know Molakule has said here the plain Jane PSF for "domestics" is a zinc-phosphorous containing fluid and there's barely any zinc in a typical ATF. Red Line, however is selling their ATF as a PSF for GM/Mopar applications.
