what occurred just prior to the loss of the speedo? sye install, x-case out for some reason, mouse found a good warm spot next to your pcm to build a nest, or did it just decide to stop working one day? some lead up details would help diagnoses easier.
sounds like you had it unhooked purposefully for some reason by the way your first post reads. if you had the VSS module out of the x-case you may just have the unit indexed wrong in the hole, not allowing it to interface the gear on the output shaft. but as others said the speedo reading comes from there at your x-case and not the trans.
