This chart at

one of the better ones.  I assume from your email address that you are in
Canada.  I'm pretty sure that there were no diesel Vanagons imported into
the US until 1982.  You can change to a different 4 speed, but it may be
easier in the long run to have a different ring and pinion installed in your
current transmission.  5 speeds are available, but rare.  I have one in my
'83.  Beware, there are many other (expensive) parts required to install a 5
speed transmission.

  HI,

  We are the proud new owners of an 81 Vanagon Diesel. The engine has been
recently replaced by a '93 Turbo Spec 1.6 Diesel. The transmission is still
the original. We are finding that the engine runs at high revolutions (3500
rpm)while driving barely 90 km/h.

  Does anyone know whether it is possible to change to a four speed gearbox
with a higher ratio, or a five speed? What are the limitations on compatible
gearbox models?

  Thanks very much,

  Wiebo Troost
