Hi All,

I rounded off the drain plug on my transmission pan drain plug (2003 Yukon XL).

I've heard this is not an uncommon problem--apparently they overtighten them at the factory and then when you try to get them off, the bolt just rounds off? Well, whether it's true or not, both I and a friend of mine had the same experience, so we now need to use a bolt extractor to get it out of the pan.

I'm wondering if any others here have had experience with getting a frozen (and rounded off) transmission drain plug out, and if so, what extractor kit/method have you had the most success with?
