You might more responses if you put this thread in the correct forum, this is for transmission questions. I got mine from the dealer a few years ago for about 5 bucks. GM p/n 1236317. I checked a few local autopart stores, but couldn't find one. They may have them now though. It's just called a Rear Axle Vent, not a plug. It's just a plastic piece that fits into the hole with a loose cap on top.
