Yes, really great data. Bryan, could you give us some details about the
E4OD in your truck.  TC

The truck is a 1994 F250  4 X 4 with a Banks exhaust system and some 
modifications done to the engine by a guy named Bryan to increase the intake air flow.
 The engine is the last of the IDI version.
95 saw the 1st of the power strokes and a different transmission. 
I am on my 4th ( I think )  transmission.

Since it is the 7.3 diesel, I assume this is the super duty version? True? TC  

Not the super duty version that came much later than my
truck  which is why I suggested checking the transmission parts
suppliers to see if the latest transmission has a better gear set or
if they overcame the problems with other changes-like perhaps
a softer shift ?

What gear was in use before the gear change? TC 

Failure has occurred 
as follows and as memory  permits--  (an aside- my wife
calls the disease  CRS  it affects my memory its long form is
known as Child Related Senility it comes from having small
children in your house. )
   Failure one- don't know what failed first -  salvaged the case 
and nothing else  Driving on flat ground at the time overdrive off.  
Loud bang loss of forward motion. The forward set ( overdrive) looked
like the pictures of the redrive failure.

   Failure two- Pump failure- limped into a dealer cooked all the 
inside parts.   the gear sets where sort of 50/50 showing some wear. 
 As it was warranty the bulk of the hard parts went back in.

   Failure Three  This time on a hill pulling in 3rd gear downshift 
to 2nd caused  the clutch housing to split in two ( we think)   This time
no hard parts other than the case and I think the tail shaft where
reused.

   Failure 4- again on a hill the shift to 2nd this time scattered
 parts over the road.  We bought a new case started over. Once again 
one of the planet sets had come apart- sorry I don't remember which one 
I got a box of parts which I left at the shop after a quick look.  
Everything showed pitting of the gear teeth consistent with lots of load.
     We have put 380,000 KM  or  235,000 miles on this truck since
brand new

What gear failed (2nd?) and which planet set is in use for that gear 
(front or rear). TC   

I would have to look in the book  but I think the front set is OD. and 
the rest off the back but don't quote me.

It should be noted that this diesel engine produces about 
1000 ft/lb torque. TC 

I think that might be high  I will look up the stock figures when I get 
a chance.  Our truck will be a little over stock.

The 13B is around 160 and a 20B about 240 (normally aspirated).

Also some pictures would be great Bryan so we can compare the damage to what
happened to Tom's gear box.

 Sorry all this is old news as it were.
The last failure was just on about a year ago.  When I blow this
one up I will take you some pictures  :-)    Bryan in Princeton B.C.
