75w80 huh? 🤔 I should change the fluid now that you mentioned it since I got it last month. But Ford recommends the duel clutch fluid(XT-11-QDC) what's the story with the 75-80?
WELCOME and CONGRATS!
The Ravenol MTF-2 75W-80 (and a few others as well) is/(are) FULLY Ford spec approved for our transaxles.
The approved MT Fluids give MUCH greater protection than the DCT fluid does to everything inside these transaxles, and most claim greatly improving shifting feel/action as well.
It also does not mechanically 'shear down' and thin out with use anywhere close to as quickly as the DCT fluids do, so yes, it's longevity is also much better than the DCT stuff.
The speculation here is that Ford did not want the bother/expense of an extra fill tank on the line, so they just used the DCT fluid in our IB6es, since our cars were/are the glaring exception of being a manual gearbox ONLY nowadays, and in Ford's lineup, save for that choice in the 'Stangs, and some very very rare Fusions.
