I do a series of 3-4 drain and refills every 30k miles (I drive it enough to get the fluid hot and have enough time to mix in between each drain and re-fill). It has been good for 215k miles.

bismic Personally I believe it is the 100% filtration.

ZMANN our service interval is a lot less with the SP than with transmissions that had LV as the original fill

you have to wonder if any of that is fluid related ? or all the filter type ?

voodooridr They are back to recommending LV again but the SP has treated me good for 15 years so I'm going to continue to use it

You're not supposed to mix them though

ZMANN Ford never went back to SP for the 5r110 but they did revert for a few other applications and that's why they never phased it out like intended

but they did not suggest mixing SP and LV right away then they came around to approving

a lot of guys use the Valvoline High Mileage SV/LV fluid (it is not a Mercon approved fluid just Valvoline suggested replacement )

jokester00 Ford has gone back and forth a couple times on this, but i'm with @bismic and use Mercon SP.

crankn101 Right on, thanks fellas. Ill refill it with LV and do the filter in a couple weeks.

bismic It is NOT Mercon V.

I get the Mercon SP, but LV works also. Even the Valvoline MaxLife has proven to work.

066 Mercon LV. Should probably change the filter too
