Speedometer Died After having my transmission rebuilt my speedometer died. took it back to the shop, they checks the sensor and connections and said it wasn't transmission related. They said I could leave it there for a day or two so they can troubleshoot. I don't have that time, Anything I can do to troubleshoot the problem? Odometer also stopped working, how do I set it at the correct mileage?

take it back the transmission shop it is under warranty for at lease a year. they did not do a good job. the shop to replace the speed sensor when they was rebuilding the transmission

I have the same issue. The instrument cluster could be bad.
If you changed the speed sensor at the transmission and still have the same problem then the issue is in the instrument cluster. You can attempt to fix it by tightening the screw or sanding the contacts. It all fails to fix the issue; buy a used cluster off eBay.

Follow the speedometer cable from the firewall, down to the transmission. It should bolt in the transmission, remove the cable from the transmission, and turn the gear to check to see if speedometer is working, if not, it's most like the speedometer head unit.

Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

You should have a speedometer cable that runs from the back of the trani, thru the fire-wall, and into the back oh the gauge cluster.

It may be a faulty speedometer with a short inside, or a short on speedometer wirings or connector.

Whenever car vibration cause the wiring to short, there you lose speedometer and trans functionality.

You need to access the speedometer connector and wirings to
instrument panel to fix this.

the tramission is not shifting its the output sensor on trasm that broken drive slowly the shop gonna pass the scanner on the trasm it should be the input and output sensor not a rebuilt trasm if the shop tell you you need a rebuilt ask for a second opignion hope it help fixya our post thanks pierre

Look on the wiring harness it plugs in on top of the transmission
make sure all the wires are together. If every thing is ok with the wiring, The sensor is the only thing it could be. A gook used spedometer sensor from the junk yard will work this sensor dosent take a lot of abuse so a good used one will be cheap and work just fine. This is a job you can do your self and save a lot of money. I had the same problem with my 95 civic
