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?

Another vote for no gasket.
On a previous truck, I installed a gasket instead of sealant. Years later during a hard tow, the gasket failed and a lot of fluid was lost, coating the hitch, where it was evident.
It turned out that all of the bolts were loose. Since I know they were torqued properly and to specs, I think the paper gasket softened and compressed over time, reducing the pressure on the bolts. I tightened the bolts, added a lot more fluid and continued the trip, but a few months later the differential was shot and had to be rebuilt.
That problem never happens to people who use sealant.
