    That is very true. The nut on the transmission yoke may be loose enough to let the tone wheel slip. If it is then the speedo will come and go check that nut first and see if it got loose and see also if you can spin the tone wheel. It shouldn't move and should be tight for everything to work properly with the speedo.

    Thank you soooooooo much. Imagine a woman telling a bunch of mechanics for years how to fix the speedo... And it worked. They couldnt believe it! They too thank you!:biggrin_2551:
