Fair enough...I was careful not to say that they meet it, but that they state they do...
As I look over the sites, they do say "recommended for use where the following..."...which is not the same as stating that it meets the spec...and the Mobil 1, which I was considering, no longer lists JWS-3309 or T-IV among its recommended applications...so, I am no longer considering the M1 ATF...
To date, I have tried the T-IV from Toyota and the Mobil 3309 in the Volvos (whose AW55-50SN require a JWS-3309) and the T-IV and Castrol IMV in the Corolla, which requires T-IV.
