Speed sensor bad.
TCM Malfunction, And/Or Speedometer Sensor Malfunction.
Why?
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
Having the speedometer jump and the engine stall in the 1994 Jeep Grand Cherokee Laredo could be a problem with the idle and the transmission. The transmission slipping can cause the speedometer to jump.
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.
Speedometer cable (most common) Speedometer head Gear on transmission end of speedometer cable
If the speedometer and tachometer are not working in a 1994 Nissan Kingcab 4X4 V6, it could be that a fuse is burned out. It could also be that their mechanisms in the undercarriage are corroded or dirty if the vehicle was used for 4-wheeling off road.

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.
The gear between the driveshaft and the transmission is broke you need a knew one
