You can use whatever you want. Just know that if you use MERCON LV where MERCON V is required you will need a new transmission very soon. I recommend having a new trans on hand before installing MERCON LV.

The AT FLUID CHART (MOTORCRAFT)
Thanks for the suggestions.
The local auto parts stores that carry Motorcraft brand oils/ATF, NONE had a "4" or that "XT-10-QLV" printed anywhere on the bottles.
Advanced brand ATF has "LV4" on the label. Wal-Mart's brand has the "LV4" on their label. I don't want to mix discount brands with the factory fill, since I don't know anything about them.
I don't understand why the Owner's Manual says to use Motorcraft Mercon LV ATF4. Then the factory Service Manual says to use Motorcraft Mercon LV ATF XT-10-QLV. Two different Ford Dealers say they never heard of the "4" or the "XT-10-QLV". Both stressed, Motorcraft Mercon LV in the 4R75E trans.
I just want to make sure to get the right fluid.
How do I get ahold of the resident trans expert Mark Kovalsky?
EVERY vehicle I have ever had since the '60's, that has a auto trans, I've welded a pipe nipple/collar on the pan for a easy drain plug. I have several made up ready to weld on, laying in a drawer.
Thanks again.

LV fluid
Hi Tech transmission, rebuilt the tran in my 2008 F150, 4r75e. I was told they use LV fluid as there is no internal difference in my 08 and my 14 E350 which specifies LV fluid. It is just that the fluids V and LV are not compatible. With a complete rebuild there is no cross contamination.
I would like to know if this rings true to Mark K?
Thanks
