For engineering types, that may not be a good enough filter. I was perfectly comfortable explaining why an automatic transmission was in the bathtub..... I wound up trying to catch well-thrown cast iron skillets. ;)

Consider the specifications and tolerances of the unit you are interfacing with. Cast Iron skillet projectiles may be within operational parameters. Idiopathic departures from normal operations can be considered within specifications in some instances, and have been known to occur without warning or apparent cause. (8^D)
Two questions come to mind:
What were you and the transmission in question doing?
She hadn't just been skunked or something, had she?
