My 86 vanagon / Karmann Gipsy RV lived / originated in Germany
for 25 years with a 1.6td. I have owned it about 5 years. Soon after I
bought it I installed a 98 1.9tdi afn. The Gipsy is heavy compared to
most t3 vanagon and the 1.6 td was a little light requiring frequent
down shifts; too many for my satisfaction.
My Gipsy has a 094 transaxle, if you ever work on / repair one I
highly recommend replacing the clips and C clips as the Bentley
suggests. It may / will save you both time and money.
