I agree, though, that it's probably just a random coincidence that one went out right after the other. It just seemed a little TOO coincidental that it happened literally minutes after the shop drove it at least 7 miles in 4WD on dry pavement.
I've heard of driving in 4WD on pavement causing damage to the transfer case and such, but I hadn't really heard of it causing damage to a transmission. I just wasn't sure if the added strain on the drivetrain could cause a transmission that was already less-than-perfect to finally fail.
In the end I guess it's irrelevant, because even if they did somehow cause it there wouldn't be any way to prove it, so I know that we're going to be paying for it anyway. The only reason I'm asking is out of curiosity, and to determine whether or not I should ever go back to this particular mechanic.
Thanks so much, everyone.
