While I was cleaning the old gasket off the wire wheel removed most of the black paint around the edges of the pan. Also i noticed that a small amount of paint could be scratched off of the inside of the pan. Is this normal for a transmission of this age or should I look to replace the pan? I am leaning towards replacing as I stripped the drain plug (it's holding fine just wont come out)on reinsertion so chances are I will need to retap the pan anyway. Just curious if I can drive it for now until I get the parts in.
