I can not seem to find a recent thread on what gear oil and ATF fellow 80 series owners are running in the recent years. Thanks in advance for everyone's suggestions.

Whatever I can get at auto-zone.
Valvoline Multi vehicle ATF DEX III or IV equivalent.
And Valvoline gear oil for diffs and transfer case. Two different viscosity ranges based on FSM.

Do you have a dealer?
When I changed all the fluids last fall I was starting to question the sanity of the different (yet overlapping) viscosity call out. Thank you for the tip, I'll update my book.

I run clean oil.
I am a dealer.
They're both 90 weight at operating temperature. The 75/80 is cold viscosity.
I'm not one to doubt Toyota engineering, but 30 years is a long time in the lubrication industry.

Amsoil is really good stuff in my opinion and what I ran in the VW transaxles I used to operate. For the my 80 it's the house-brand/cheapest at Oreilly's just down the street.
Running 80w-90 right now but going to go to a heavier weight in the rear to try to quiet down the rear auto locker
