I would like to change oil on the automatic gearbox, I know it is premature at only 10,000km but I would like to remove any residuals from break-in, but I have the following doubts:
1) What gear box does our car? The initials Fiat AW6R31 which then pretend to be Aisin B400, while on the sister mx5 it is called j6a-el /1 now here comes the big doubt, from several searches on forums and spare sites for automatics it is not clear if it corresponds to TB65sn (320nm) or TB61sn (480nm). The Toyota gt86 and Subaru brz should also be fitted with the same TX6A-el gearbox
2) jws 3309 or 3324, fca it seems that on a vague document it has changed specification to 3324, here in Europe we have no knowledge of it, while Mazda recommends the 3309 and Toyota 3324. what a mess !! I understand that from 3309 to 3324 many things change, besides the flashiness, also the additives and the base, the first is mineral and the second synthetic, therefore two completely different oils, even Toyota explains that t-iv and t-ws are not interchangeable. So I wouldn't want to put a universal oil, I would like to stay on one of the two specifications but which one?
I would like to share with you my info, maybe im wrong or maybe some of you have direct experience on the ATF oil change, I hope it is an interesting discussion and manages to resolve my doubts.
