Hi so a mechanic needs to do that one. A FORD dealer.

Speed sensors are the input and output speed sensors on the transmission which determine the shift points for the tranny. The vehicle goes into fail safe mode when either one goes bad.
If the speedometer isn't working the the sending unit for the speedometer is located on the differential portion of the tranny.
Do a search on youtube to figure out what you're after and how to replace the part.
