[Healeys] OD drips

[fsufan1952 at yahoo.com]

Good morning all 
    Two days ago I installed a new washer on the large brass drain plug on the 67 BJ8 . Filled the transmission up . Looked at it in the morning and it had drips on the bottom of the plug . So I used the correct tool and tried to tighten it up . Then this morning looked again and there was those drips. When I installed it the surface didn’t look gouged or anything. So what’s the fix to stop the drips ?  Remove the big brass plug , get a new gasket for it , apply some kind of gasket sealer on the gasket, reinstall it and tighten as needed? Maybe add two gaskets ? 
      Thanks as always, Don
