Specifications for several 3309 ATF fluids

Valvoline
The Valvoline link above is for engine oil. Here is the page to select ATF (and two maxlife ATFs that mention JWS 3309 Aisin Warner and Toyota type IV) - the import version is higher viscosity:

And the name of the ATF specification is JWS 3309, not Mobil 3309. Other oil processors definitely make their own versions of ATF. However, it is difficult to know who supplies the ATF when you are looking at a bottle and its brand. I suspect that Toyota does not make Toyota T-IV and I do not even think that Aisin makes theirs, although I do think they specify its characteristics.

I read the spec sheets for Mobil, Aisin, and Idemitsu. It appears Idemitsu has the highest density and Aisin has the highest viscosity ratings.

I'll take driving videos before and after filling with Idemitsu then report back.

Thanks for the SPEC sheets EngineeringBloke.
