Opinions on 4 speed with OD

I've locked up a center chunk before, at speed. A cup rolled by and made the " push it outta the road" motion. We laughed at his ***. Sure Grip w/ Sticky Mickeys.... ain't Happening! Also trashed an input shaft before. Ain't moving...

I shifted a powerglide into reverse at 65 once. I made the shift, locked the tires down until I realized what happened and I got it back into D. We never tore it down, but we kept driving it until I sold it a couple years later. It didn't affect how it shifted or pulled at all. I always figured it twisted the input shaft.
