OVERKILL
$100 Site Donor 2021
Dumped the pan and filled with Motorcraft Mercon V (black bottle) today in the Expedition.
Vehicle is a 2002 with the 5.4L, and 4R100 transmission.
Shift firmness impact was substantial. Shifting is MUCH smoother. I don't know if this is a good thing in a transmission that does full-power upshifts into all 4 gears but it feels nice
I can no longer feel the downshifts. I could always feel it shift down into first as I came to a full stop. Not now.
Converter lock/unlock as the truck up-shifts is now smoother and seemingly quicker as well.
I am VERY surprised.
