The rear transfer housing is pretty isolated from the rest of the transmission. I would have flushed a bunch of brake clean through and out the front drain plug, cleaned the magnet off, and run it. It's an in-car fix at that point because you don't have to pull the trans.

Make sure they know it takes the WRX only 1.1:1 reduction rear transfer gears, not the 1:1 ratio that every other subaru uses. Otherwise you will get bad binding when you try to drive it.

If the snapring didn't cause it, donuts or powersliding from loose surfaces onto pavement can do it. So can vicious launches.
Thanks for the input. P&L Motorsports is handling the teardown & rebuild so I'm sure they're on top if the little details. If the rest of the trans is trashed I'll just be going with a LGT replacement.

The snapring hypothesis is interesting. I'll do some more research as that's a new one on me, so thanks. I'll also be curious to here what they have to say. Like I said, no launches of any real note (2k maybe on a tare and certainty no power sliding, donuts etc. A little mysterious. But I am the 3rd owner, so no telling what sort of life it led before me. Thanks.
