The Motorcraft lube is coursing thru the veins of my CSS. On day 3 of my Indy DE last Aug, I started to have issues with the 3-2 downshift. It could be crunchy at times. It was my original trans fluid. Got home and started researching the flushing process and fluid options. Heard the Motorcraft was good, so I tried it. Fixed the crunchy downshift, but is a bit stiff until warm on winter days.
My CSS had 53K mi when I did the change, including 4-5 DE weekends per yr over 5 yrs. The viscosity of what came out was extremely thin, even compared to what was going back in.
