Other than Toyota, anyone have suggestions on oil brand/type for the W59, TC and Diff?

W59? (http://en.wikipedia.org/wiki/W59) ;)
If money is no object, I've always favored Redline 75w90 in the diffs, and MT-90 in the tranny and tcase.
But if money is an object and/or you have OCD about changing your oils at frequent intervals, then a name brand GL-5 in the diffs, and GL-4 for the tranny is good to me.
i use whatever 75 w 90 is there dino with quart of lucas heavy duty oil stablizer i change my diffs and tcase at least one or two times a year depending on where and what driving

MT-90 for sure in older trannys and transfers. The newer synthetics and some dinos have additives that erode the brass bushings.
