Tranny leak from new drain plug

[Roc87]

I had my tranny rebuilt around 5k miles ago, and just did the first service to it on Friday. Also installed a drain plug on Friday, since Art Carr didn't send the correct drain with all my parts 5k miles ago. Now, no matter how tight I get the plug, it's still leaks! Anything I can do besides buy an aftermarket pan with a drain already in it? The drain plug is a Nut welded to the inside of the pan, and a plug with gasket on the bottom of the pan.

What kind of drain plug gasket is it?

If it's a nylon gasket, good luck getting it to seal. A much better idea is a captured O-ring gasket, like most of the OEMs use now for oil pan drain plugs. It's a metal washer with a molded in O-ring. They won't crush out from under the drain plug and deform like the nylon ones, and seal much better.
