Re: 200TQ speedo shakes, odo stops

The problem is a bad connection between the speedo unit and the rest of the
instrument cluster (IC).  Nearly two years of frustration were needed
before the solution was found.

The speed sensor reed switch of the transmission was replaced and this did
not help.  Surgery on the IC was required.  This most definitely a DIY job
provided that you are comfortable working with solder.

Remove the IC.  Open the rear.  Extract the speedo.  Easy job once it's
open and you can see what you are doing.  Replace the four electrical
contact pins of the speedo with four wires from a nice four pin electrical
connector (I used an RJ-11 telco plug/jack).  Observing color codes, solder
the other half of the connector to the proper places on the PC board of the
IC where the two pins used to contact.  Connect the two halves of the
connector.  I placed mine outside the rear of the IC to allow easy
disconnection for the next time I had to get into the IC.  Unnecessary as
it turned out.

If you need specific help, lemme know.
