On a 2011 Ford F250 with AOD transmission electronic limited slip do you need to add a friction modifier when changing the rear differential oil....thanks

if it has the e-locker it doesnt need friction modifier. just needs to meet ford's specs. in my 16 with e locker i have run valvoline for the last 25k miles since my gear swap. ill be changing it in 5k miles.
