I believe the accepted thought is the LBA will permanently stop the explosions. It wont. Less likely, yes. but still possible. The only true 100% fix is to replace the clutch drum. It ends up costing slightly more than the nice tranny shield that the schrapnel can go right thru.
I think of it as taking the detonator out of a bomb, but leaving the high explosive and calling it safe. It's safer, but still the main explosive power is there.
There was a post I think on Moparts about a fellow with a 1/2 ton truck, racing a 500" witha Gear Vendors who was shifting to first-over while racing. It was flattening the teeth of the overunning clutch every time. This is what leads to the drum explosions. he was very lucky, but had to pull the trans and spend another $600 on a drum and the LBA valve body for it.
