To help with the snap ring question...the way I understand it, most of them fail by around 40-50k miles if they're going to. Mine is within range, and without failure at 125k miles, and the case has never been replaced. That doesn't mean I beat on it. I'm apparently one of the lucky ones, but I'm still going to be very careful with it until I can get the case and associated parts replaced. Just be mindful of what these guys are saying. Also, a couple of things I didn't see mentioned, if you start having problems with the transmission popping out of gear or making a whining noise that is unusual. Those are (according to what I was told by Wade at SoS) the most noticeable signs of failure.
