You should at least see an indication it just might not be correct, with the cable disconnected from the speedometer do you see the cables center rotate when you are moving forward?
Some one can just watch the end while you drive or if you have junk laying around like I do you have an old speedo or a mechanical tach that you can test with.
This will check that you are getting drive from the rear.
If this looks OK, I always keep a short piece of speedo cable handy to chuck up on the drill for testing the speedometer itself.
Once you get a indication, then work on the rod for speed shift to show proper speed.
