I am currently using Mobil Multi Vehicle ATF

It meets Dex III, which is what was originally specified for this box
Mobil Dex VI does not list TES389 as a spec it meets.

Can Dex VI be used? Is it any way superior to the Multi Vehicle ATF, which is also a synthetic blend? Is there an issue with viton seal compatibility?
