	I also looked into this matter when searching for a good trans
synth oil for my 4000s. I was aware that the MT90 was the "proper"
oil but I could'nt find it locally. Ended up using MTL and am very 
satisfied with it. No leaks and it cured a morning shift-reverse grid.
Been in there with no ill effects for ~30 K miles.
