Where is the speed sensor located in a 99 Mitsubishi Eclipse?

1-Take the battery out

2-Remove the battery tray

3-You should see the black sensor on the top of the transmission on the back.

It takes a 10mm socket then it should lift out.

Take the plastic gear off and see if the shaft will spin with a drill with someone in the car watching the speedo (the car has to be on)

If it works, then just check all the connections with the wires and the gear to the tranny.

If you can stick your whole fingers through the hole and spin it...the whole tanny has to come out to replace the gear ;)
