tranny went bad on type44. Shall I be surpised?

[kbogach]

Roy, I will jack up the car tomorrow and measure it more accurately, but 
I think it was much more than 1/8''.   I am also very curious about the 
failure.   I wish I new more (anything) about transmissions.   One thing 
I don't understand is why there is no any noise from it if it is that 
severely worn out.   I also can not understand from looking into Bentley 
how differential cooperate with the rest of internals.   Is it possible 
that the diff  has a play due to wear in some other parts but not in its 
bearings?
I also could remove the plug and see if it has metal shavings.   It has 
a magnet attached, or magnetized, correct?
Thanks a lot for the experiment.  I will report more accurate 
measurement of the play tomorrow.

Konstantine.
