so its a 93 legacy auto trans. It was involved in a little front end wreck and now put back together, but the spedo does not work. No check engine light or anything, is there a cable or is it electrical.

cable, from the right hand side of the trans near where it meets the engine to the back of the speedo.

 

it could be the speedo drive gears inside the front diff, but the cable is more common.

so i pulled it off the trans i pulled the cable out of the housing and it looked good, put it back in turned it by hand until it went up a tenth of a mile, so i put it back on and still nothing. Is it possible that where the cable meets the trans, what ever that part is that threds in to the trans is bad or is it the gears as mentioned?

i have never taken one apart that had a cable, so i do not know if there is a piece inbetween the cable and the speedo driven gear shaft. probably not.

 

if you do a search here, you will find other a couple of threads on this subject or close but usually on newer trans w/ speed sensors.

 

you may get an understanding of how it works by searching here:

So problem fixed, cable not the problem, but where the cable meets the trans the, cable housing clips too and then threads into trans, inside this, there is a little piece that looks like a flat head screw driver, goes into the trans, and on the other the cable slips in. This piece had broken, so when the trans spun the piece the cable did not spin.

You need to make sure you get the cable seated correctly in the speedo drive (end of the cable into the slot inside the drive). Or you'll shear off another one trying it. Also, don't pull too hard on the cable, it's really easy to pull it off the back of the speedometer.
