Thanks for the replies gentlemen. I do have the shop manual. I just don't see in the manual whether or not I can pull the back housing off while the unit is in the car. The overdrive is working. I've pulled the cable out of the housing and it is good. the driven gear is good as well. It is securely fastened to the piece it attaches to. The end of the cable is square and the gear assembly definitely drives/spins the cable. I am certain that the cable housing end is seating completely in the trans/overdrive case. I can stick my finger into the case and easily spin the drive gear (yes, the one in your photo) on the output shaft. I don't have my manual here with me but I'm quite certain that it states that the speedo drive gear is keyed to the output shaft. Perhaps there were/are variations? It stands to reason (at least to me) that if I can spin the drive gear with my finger, the drag on the cable spinning in the housing is preventing the gear from turning with the output shaft. I don't know if the trans was ever replaced but it does not appear to have been. There is enough crud caked to everything that if it ever was changed, it was long ago. The car is all original, solid and rust free with about 70,000 miles showing. With my newfound knowledge, thank you Fid, I'll yank the back of the overdrive and see what I find. Nothing is impossible to fix!
