The speed sensor tells the ECU how fast the car is moving across the
ground.  The tach tells you how fast the engine is turning.  These are
two rather different things.
  There is no obvious reason that a transmission replacement should
affect the tach at all.

You know, Scott would certainly want to know what year your van is, etc.  :-)

Assuming you are using the VW tach, info about it was connected would
be helpful.

I have a 1995, EJ22 and believed the speed sensor was needed was needed after 1994. Scott?
