H23A1Lude

I have a 94 Prelude.
I just looked under it, and it has three leaks. One is the drain plug.
So can I just put some sealer around it without taking it out?
And the other two have me stumped.
One is near the bottom of the tranny, and the other is over about a foot.
I think it only leaks when under pressure. But I don't know. Suggestions?

Me: No you idiot.
