Differential fluid change
OK this is my first time doing this. I have the correct fluid and I hope the correct gasket. My question is: do I use permatex on the gasket or leave it clean?

Thanks for all the replies, I'm off to get the right permatex.
I got the fluid as specified in the manual, no friction additive that's was for older models I think. And I have a little pump for the fluid and a 20V Dewalt impact wrench for all the bolts.

Last week I changed the rear differential gear oil on my 2011 F150. The spec call for 75W-140 full synthetic with a friction modifier added. I used ultra black permatex on the case cover. Everything went great. The bolts on the differential are to be torqued to 33 lb-ft.
Agesilaus, sure hope the /0volt impact wrench is for removing the cover and not installing! Always best to tighten bolts to the correct torque during install.
