So they only had small jugs of that fluid so I went to ruralking and got there brand of gear lube "harvestking" gear lube 85w140 conventional GL-5. and I have my old gear lube draining still.... it's about 20°f outside so its draining like molasses on a cold winter day. But it seems to be in decent shape not milky and no metal chunks or flakes so far, it is obviously pretty used tho as its rust brown in color.

And my selector had some red color oil in it. Could have been "atf" or some brand of oil that adds a red dye to it.?.?.?. Anyway I added 10w30 engine oil to it and also carved a new gasket out for the front plate as the old cork one ripped when I took it off. And everything seems to be in good shape inside of there.
