Looking for 700R4 expert

I have a '71 C10 with a 700R4 in it. A year ago I was pulling out a side area of my property and ran a bit into a berm, gunned it to get up it a bit so i could back out, and all of the sudden all gears just went out. The parking prawl engaged, and i went underneath and shifted it by hand to be sure that it was actually shifting. But reverse, 1,2,3,D nothing would work. Checked fluid while it was running and it was full. No burnt fluid, but when pulling the pan the entire thing had about 1/16- 1/8th of an inch of metal slivers in the pan. The trans was rebuilt about 2 1/2 years before this. I'm just wondering if anyone can point me in a good direction to get started diagnosing?

Thank you!

This is meant as a snarky comment by any means. Unfortunately, it sounds like it's going to have to be rebuilt again. Clinebarger is our local 700r4 resident expert. Hopefully he will pop in and see this.

Kinda figured, thank you though! Hopefully Clinebarger can chip in but until then I'm just going to assume it's toast. Again. Lol

Snapped the input shaft out of the input drum?

Hmm, could be. Honestly anything helps here as i have no clue about automatic transmissions haha. I have a second car so i wouldn't mind learning a bit but I'm probably just going to end up throwing this at a shop. Idk why, but it seems a lot more complicated to me than an old SBC to rebuild.

If the shaft snapped in the input drum what would be the easiest way to go about checking to see if that is the problem?
