ATX trans gasket

[JET DH]

So I changed my transfilter with the Fram kit a while back and since I've had a leak coming from somewhere. I can't find the leak itself, but I'm going to try the simple stuff first.

My question is what is the best way to make sure it is sealed completely?

I'm kind of thinking that if I just use the gasket, it may get a tear or something and I'll be back where I started. If I use some RTV as backup, I am thinking about putting it on the pan then putting the gasket on the RTV, and installing the pan creating a sandwich kind of seal. Or I could put the RTV on both sides of the gasket, but I think that may be overkill.
