First question is, what makes you think the sound is coming from the
overdrive? Not that I doubt you, I just don't know how I would be able to
tell that from the driver's seat. Since the overdrive should be
automatically disengaged in first gear, anyway, I would think I would be
more likely to attribute any grinding noises to the gearbox, unless it was
obviously otherwise... but what is it that makes it obvious?
Second question, when the OD failed to disengage upon turning off the
switch, could you tell if it remained engaged even after changing gear, say,
down to 2nd or 1st? Because if it did, and you subsequently selected reverse
with it still engaged, everything I've read about ODs suggests that it would
be permanently damaged. Which would certainly explain that grinding sound...
