Speedometer Problem

[GWAPITO69]

i recently change the gears on my odometer but now the speedometer and the odometer are not working. i checked the fuse but it was good, i check the wiring and it was ok then i change the speedometer sensor but still no response to my speedometer. do you guy's think that my speedometer needle is bad? what do i have to do to get the sppedometer running. this is the only thing that keeps my car in the garage.
