The gear between the driveshaft and the transmission is broke you need a knew one
The speedometer on the 1994 z28 Camaro has both MPH and KPH on it. The KPH are the red numbers on the inside of the scale.
Why?
A worn or frayed speedometer cable will make the speedometer shouter. As the speedometer cable becomes more frayed the speedometer will eventually quit working.
If the speedometer and abs light are not working then you have a speed sensor problem. If the speedometer or odometer are not working then you will need to take it to the dealership and have them send it off for repair.

I just acquired this 1994 jeep wrangler and the speedometer does not work. I understand it does not have a cable, so if it is electric i am lost . Help
You can fix the speedometer in your 1994 Oldsmobile 98 by replacing the speedometer cable. If changing the speedometer cable does not fix your speedometer you will need to replace the entire speedometer.
If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable
