Question about 1993 Ford F350
Mounted on top of the rear differential housing,facing up and slightly forward is a speed sensor that is common to go bad,this is the Vehicle Speed Sensor (VSS).Replacing it is pretty easy,or it can be tested.There is also a PSOM mounted up under the dash (Programmable Speedometer Odometer Module),and these also are known to go bad.Ideally,a scan tool would be available to look at the VSS reading in the data stream.If the vehicle computer is SEEING a constant and steady vehicle speed signal FROM the VSS,then you know the VSS is functioning properly,and the problem will likely be with the PSOM.If the vehicle computer is NOT seeing a vehicle speed signal from the VSS,then you know it's a bad VSS or the wires to and from it.Good Luck.

On the top of the motor there is a sensor just behind the oil fill cap. This sensor controls the tach and the trans shift points and torque converter lockup. If it is not working it will burn up the torque converter and trans.
