speedo stoped working

The spedo om my 2004 tacoma stoped . I have taken a quick look under to see the cable and along the fire wall. and did not see anny thing that looked like a cable. Does anny one know I can change out the insert with out the changing caseing and where it is I don't even see it going in the the tail stalk of th tranny. sorry for the poor spelling just finnished night shift.

 

Thank you very much I will fiddel with to to see if I ca get it going

 

The speedo on my 2004 tacoma started to work again on its owne for a COUPLE OF WEEKS. But seams to work for a short time then stops. Is the sensor located on the right side of my tranny? I should also explain this is a standard shift 4X4

 

Can the sensor just be removed and replaced or does it need to be calabrated?
