All the Multi-vehicle ATFs claim to be meeting it without much explanation of what it means. Are the Japanese manufacturers uniting behind a standard in the face of D-VI ? Are there serious tests required to meet this standard ? Is an ATF with this approval better than one without ?

Castrol Import Multi-Vehicle ATF exceeds the requirements of the JASO-1A performance standard created by Japanese Automobile Manufacturers. This standard is recognized by Japanese OEM's in certifying ATF for use in their vehicles. Consequently, Import Multi-Vehicle ATF has Castrol’s first ATF performance claim: “Superior Performance for Maximum Transmission Life”

there are no API standards for automatic transmission fluids. Indeed, it is only in recent times that the Japanese have released a draft general industry standard that stands alongside
their individual requirements. (JASO M315-1998, now called JASO-1A).
Afton chemical rep talking about Mercon LV mentions it -

"Another key demand is for greater friction stability. We've seen this emphasized with General Motors' Dexron VI fluid, with the JASO specification in Japan, and now Ford's Mercon LV. The OEMs want consistent friction performance -- shift feel -- throughout the life of the product, and for the product to have a longer life as well."
