Not necessarily. I had a tough old Chrysler many years ago that I wanted to shift into neutral to coast down a long hill to a stop sign. I accidentally stuffed it into reverse at 55 mph. That hammered pretty hard on a bushing and it developed a flat spot and a pulsing torque converter vibration, only I didn't know that was the cause until a few years and many miles later when it started dumping fluid on the ground only when the engine stopped running. The vibration pounded on the torque converter's hub until it cracked and broke away. Being the uncommonly reliable car it was, it still got me 80 miles to home after the horrendous banging started.
The way you described what it felt like, I don't think you hurt anything. What is more likely, if anything, is you may have hurried up a future failure. Perhaps the set of clutch plates in one of the clutch packs will start slipping requiring rebuilding the transmission at 245,950 miles instead of not until 269,396 miles.
