Hi,
         I strongly suggest that the  lock ring / big C clip on the main
shaft
behind the reverse gear be replaced anytime you take a 094 transaxle apart.
Mine broke / shattered and caused some major damage to some main shaft
  gears and the main shaft bearing.  I now have it back on the road and
all appears  to be working well and ready for a Florida trip.  Early
last year
I replaced 5th gear with a 0.073 to reduce the rpm on my 1.9 AFN tdi.
          By the way I sometimes learn things the hard and expensive
way, maybe
some of you can learn from me and save yourselves some heavy greasy work.
The Bentley on page 35.84 states  CAUTION Always replace the circlip
during repairs.
