jeep auto trans pan leak

Changed the filter and oil in my 02 wrangler 6cyl auto.The original gasket was made of steel with gasket material on both sides.I went to napa and got a kit that had a rubber gasket in it,it said to use no sealer.Well it has a small leak,pan is in good shape and tight.Do u guys use sealer on the gasket or should i try to get a mopar gasket.

Your original gasket should be re-usable.
