92 cherokee speedometer failure

My speedometer on my 4.0L automatic 2 wheel drive cherokee has stopped working. When it broke, it acted like it was a speedometer cable breaking, but then I heard that there isn't a cable on this car. So I replaced the speed sensor and still nothing. Any ideas?

it sounds like the speed gear in the rear trans. tail housing is shot to hell very cheap part and easy to change if you are handy. it is a gear that goes on the rear shaft in the tail housing it turns an orange gear which turns the speed sensor. did it my self 5 days ago. need more info email me [email protected]
