These type of explosions are somewhat rare, but if one ever happens to you, believe me you will remember it. There are a number of factors that contribute to this type of failure and even if you disregard the warnings about low gear burnouts with a stock trans in the drive position or the same low gear burnouts with a non LBA valve body, you will likely get away with it for a long time. You may even have a driveline failure, repair the failure without inspecting the transmission and still get away with it. The key is that in order to have a failure of the roller clutch that creates the condition that overspeeds the drum, the little legs that position the wave springs and rollers have to get bent over enough to let them fall out of place plus you have to have enough of them fall out of place so the roller/sprag ceases to hold any longer. This doesn't happen everytime there is a driveline failure or driveline shock and the explosion does not normally occur until after the driveline has been repaired and the car is back on the track. It may happen the first time back or it may take many more burnouts/launches before it fails.

If you choose to ignore the warnings, that's your choice and no one can change that but there are others that would rather not take that chance and take steps to reduce the possibility of this type of failure.
