What exactly seems to be the problem? Do you have a digital speedometer or analog speedometer?
the problem most encountered with a bad speedo is the gear in the transmission tail cone housing. make sure it isn't stripped the other problem could be the speedo itself. If it's analog then somewhere in there it is stripped out. If it's a logic type then usually the pulse board is gone.

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.
buy another one from a breakers yard
probably a broken cable drive.
The most common reason for a speedometer to fail is a broken speedometer cable. Loosen the nuts on each end of the speedometer cable. Remove the speedometer cable retaining clips. Reverse the process to install the new speedometer cable.
