It is likely those metal shavings were produced by damaged synchro(s). According to my research and personal experience most synchros are damaged by clutch not disengaging properly (look-up: clutch dragging), very few gearboxes come from the factory with synchros already damaged or weakened.
Because of that I would strongly push them examine the clutch because if it has a disengagement problem it will keep eating synchros and therefore gearboxes. That's what was happening in my case anyway: I hope you have better luck. |
My guess is that they'll probably look at it and replace the whole unit (clutch, pressure plate, gearbox, etc.). I'm sure BMW is curious as to why the box failed in this manner.
Hopefully it's just a bad box. It happens.
