I agree with Wes dont plug the breather hole/tube. It will just start other problems like he said. I think the only way to replace it is to pull the front pump out. Why it is leaking to start with is the big question. Might be overfull, or something internal. Ther was a GM recall late 80s-90s that you slide a hose over the tube and run it down the side of the tranny so that when or if it got really hot it would puke the trans oil on the ground not on the tranny or exhaust and start a fire.
