Why transmission wont shift speedometer doesnt work ford aerostar1996 3 liter v6?

Hopefully the simple solution would be the fuse 15a for the speedometer. If the computer doesn't read the speed, the tranny doesn't know when to shift. If the fuse is alright, you then need to check the speedometer sensor located on the rear axle hub. Check connections for corrosion and cable for damage. After that, good luck !!
