What type fluid does an AX4N transmission use?

No one knows, its written on the transmission dip stick I read somewhere that 98 and newer had V which is synthetic but Pre have ATF because mercon does not exist, but it needs Mercon M what ever that correlates too which is nothing, so the answer is a crap shoot, V probably works fine, but the transmission sucks so i wonder if thats why they started using synthetic you can tell by smell I used V and it Smells awful like dead fish, what ever is inside did not smell like V. SO i do not recomend V anyway good luck if you find out let me know because no one knows.
