remember the tc holds about 8 quarts of fluid, its all tainted. and since your torn down that far, just inspect everything, get new clutches and new hardened 4 th gear hub and a new TC. and new sensors pcs and tcc. no sense in using used sensors if you went this far. and these 2 can be a problem down the road.
for all you know the tc exploded. that would explain the shards, its got like fan blades in it, like a turbine.
