I just bought an 87 model, speedometer is not working. The cable seems to be okay, I took cable loose from transmisson and hooked up a drill to it and it worked. So i figured it was the gear that goes inside tranny. I jacked up rearened with the cable unhooked and the wife put it in gear so i could watch to see if it would turn. It seemed to be turning okay until i put my finger on it and it stopped with just little force on it. You let off finger and it starts turning again. Does this mean i need another gear dilly or what ever it is cslled. If so can you get it at parts sotre? Thanks for any input.
