Anyone analyzed the WS compatible synthetic transmission fluid from AISIN. Its called ATW+ compatible with WS ATF and many more. The Russian oil forums have some good info and discussions regarding this oil. It seems the kinematic viscosity seems to be a tad higher. I am replacing the fluid on my FJ Cruiser as I was not happy with the last drain and fill at 20000. http://www.exedy.com.au/assets/file/AISIN_Fully_Synthetic_AFW_Multi_Product_Datasheet.pdf
