Yes I am interested in improving the life of transmission and ptu by improving the fluid. I understand that the ford has specifications on fluid but does is not say to not change the fluid until 150,000 miles. i question the life fluid idea from the factory, I can change the fluid early with Mercon ULV and have but I was wondering about trying another type. On the Motul website when you put in the vehicle information they recommend Motul ATF VI so I thought it was interesting.
