Where is the speed sensor located on a 1995 E 150 5.8 it's not on the back of the tranny?

The speed sensor for the speedometor and cruise control should be on the back of the transmission. There is another speed sensor on the top of the differential to indicate one wheel spinning and the other wheel rotating slower. There is another speed sensor on the front and back wheels to control ABS. Which sensor are you looking for??? Joedi
