Thx to those that sent along ideas on my original post. To recap: FJ40 12/79 manufacture date. Speedo worked but was kinda wonky - needle would flutter & fluctuate 10-20 mph. Replaced speedo cable, then speedo would not register. Then replaced the small gear & housing where cable goes into tranny. Can get the speedo to work when manually spinning that gear, but speedo still does not work. What do I try next? Do I have to open up & go into the tranny? Thx in advance for your thoughts.
