well... I would have liked to vote torco, because they make awesome oils, and i would've ran it, or voted atf, because it's real close to what i do run.
i run gm autotrak II. the main reason i had to search for the right oill and chose this stuff, is that i needed to perform below zero in regards to clutch operation. it's designed to perform in both planetary gear systems, and wet clutch operation at all temperatures. it also highly outperforms atf in it's designated aplication- automatic tranfer cases. proper coushining and viscosity, without hindering the holding ability of the clutch. so far, i am extremely impressed with the oil. absolutely no unwanted slippage, or signs of wear. neutrall became 100x easier to find while running.
it's just what i found, but i won't swear by it or push it on anyone, untill i have at least a year of good performance without complaint. it's about $8 for an oil change, and i did so, before i went out for a 4 day ride, and the oil was pretty much the ame as when i put it in there with 10+hrs. on it, but it was the 2nd oil change, and i wanted to make sure the previous oil was flushed completely.
