MTX75 5 speed transaxle fluid
I was searching up and down and all over looking for what fluid to run in my transmission. Ford service information says run their Synthetic manual transmission fluid and everywhere online was telling either 75w90 synthetic gear oil, Royal Purple synthetic manual transmission fluid and 15w40 diesel motor oil. Found out the correct fluid to run from a Ford master tech which is Mercon V because it is a synthetic fluid, Ford now recommends Mercon VI but it is dealer exclusive from what I have been told. Focus shifts so much smoother it feels like a new transmission. Just wanted to clear this up for people so you don't have to do the searching like I did.
