Stuck in the Snow/Mud

I don’t think so. Since you were on grass that was covered in snow you never had the traction necessary to do damage to the tranny or the clutch. If you raced the engine to 7 grand you might have hurt some engine components but I highly doubt that you did. Spinning the tires is a form of recreation for some of us and if done right you can do this on dry pavement with no damage at all. I love the smell of burning rubber in the morning.
