Got it. To each their own. Personally, the trans is to valuable to the life of the vehicle to use anything other than oem spec fluid. That's a personal preference.

Valvoline maxlife ATF is totally fine, if anything it exceeds the spec... but I agree, you should buy what gives you the warm and fuzzy. I have bought OEM in the past just to sleep better at night before I knew any better.
It should be noted that Toyota doesn't even make their own fluid... and if you go to the dealer for a flush, sometimes what goes in is whatever the flavor of the month is, from a 55 gallon drum from the lowest bidder. That's just how they roll.
I use Toyota Type-IV in my 4 Speed, You can buy OEM but it should be noted that its just Mobile ATF 3309 for anyone shopping around. Generally around the same price anyways.
Last time I brought in my own non-oem fluids for my front & rear diff and transfer case the service adviser ended up telling me we use the exact same thing. And I got that for free from a friend that works at a GM dealership... Some MOC brand or whatever it was.
Even the service departments don't carry the Toyota branded OEM Genuine Gear Oil. Could not get it even if I wanted it, but it does exist.
