Both fluids can be mixed as per Ford TSB. The last time I drained 8 quarts of SP out, I replaced it with LV.

Tech tips
Approval to Service ALL 5R110 Automatic Transmissions with MERCON® LV
Beginning immediately ALL (2003 to 2010 MY) 5R110 automatic transmissions can be serviced with MERCON® LV automatic transmission fluid in place of MERCON® SP.
Initially only the 2009/10MY 5R110 automatic transmissions were filled and serviced with MERCON® LV. In an effort to reduce complexity, Ford Motor Company is allowing all previous model year 5R110 automatic transmissions to be serviced with MERCON® LV automatic transmission fluid. This pertains to top off as well as fluid replacement. Mixing of MERCON® LV and MERCON® SP in the 5R110 transmission is acceptable. Extensive testing has been performed to insure there are no functional or durability concerns with the use of MERCON® LV in the 5R110 automatic transmission.
Vehicles affected are F-Series Super Duty trucks (including chassis cab, motorhome, LCF).
Motorcraft MERCON® LV is now available in three sizes:
Part Number: XT-10-QLVC - 1 quart
Part Number: XT-10-DLV - 55 gallon drum
Part Number: XT-10-BLV - Bulk
Further information can be found in the Workshop Manual, Section 307-1, Automatic Transmission

thx // I know Ford caused the confusion when the LV was first released because they didn't
have all the compatibility testing complete
FYI just for those who haven't seen the description
LV = low viscosity
SP= shutter proof

lol?
the 5r had shutter issues at first so this fluid was the fix
however I have no documentation on hand to back it up
,, the sp was a lighter fluid and so is the lv so i think that the viscosity was the real fix for the shutter
?? maybe Mark K will chime in I am just guessing at this point

Hi Mark !!
only going by what I read not by first hand knowledge like you have ..
here and there
SP was made specifically for that transmission and the SP is short for shutter proof
so I just related it to the issue .. and if the wrong fluid is used there have been shutter issues

I assume you have the newest flash. Was it showing the wrench light for temp differences? I've been wondering how much you can rely on this for oil cooler/EGR cooler failure indication. Not trying to hijack, just this statement really interested me.

I have the latest flash but the light had not come on yet. The dealer went by the gauge readings.
