418A seal

[dodge78 90]

I am trying to determine which seal I need on the side of the trans. Where the blue goop is. I think its #10 but what a second opinion. Also , is this like a freeze plug? Can I drill a hole in it then put a screw in and pull it out? Or do I need to dismantle the trans?

thanks

Not positive but I think that may be the end cap of a bearing, if it is you will have to split the trans and change the bearing, but again I'm not sure I know on the older trans that would be true.
