Is that a correct assumption?

Are you talking Trans or rear? If you read the other thread you'll see I used it in both despite the critics. Eneos is marketed for it and has been formulated to deal with the sulphur issue. Not all GL-5 spec oil has apparently. Car is running and shifting great. If you're not sure, then MT-90 in the trans, and a GL-5 spec in the dif.

Thanks for clarifying this. I am planning on replacing all of those fluids in the next few weeks. I just think I did not order enough MT-90 now. Doh!
