Hoping someone can help out on this one. I am having a hell of a time keeping the stock TC drain plug tight. It seems to back off and come loose after about 2-3 hrs of driving. I am using this one from specter:

about half way down the page. I am using the stock gasket (metal) and have tried, locktite, permatex gasket, etc. with no luck. Was wondering if anyone else has had this issue. Maybe go back to using the stock drain plug? I was thinking of using a large lockwasher to put some tension on the threads? Any help is appreciated. TC is an august of 73 FJ40.

Thanks,

If you are tightening it with just a hand "allen" hex wrench, then you might attach an "allen" hex bit to a torque wrench and tighten it to factory specs. IIRC, sor's allen plug is pipe-plug tapered, so I would use a little anti-sieze to lubricate the threads and thereby get more plug thread travel into the case while causing less thread galling. Make sure no anti-sieze gets in the case and mixed with the gear oil because anti-sieze has metal in it that might be slightly damaging to the bearings.
