Okay, so I took off my oil pan and put it back, for some reason there is this hole in my tranny that keeps leaking tons of oil. Did i not seal it good enough. because I think i sealed it pretty good. Have this happened to anyone before?

 

You probably disturbed the rear main seal putting the oil pan back and that's where it's leaking from not the oil pan itself.

 

Did you replace the seal that goes beween the oil pan and the block? There is one is the front and one in the rear. You should have replaced the seals, when putting back the oil pan and use gasket sealent.
