Bad speed sensor.
Trans output speed sensor.
according to the owners manual this could be related to a problem with the ABS. I have the same problem and am looking for a diy solution. also from the owners manual the ABS controls the transmission , and my transmission is shifting roughly, which is what I noticed before I noticed that the speedometer wasn't working.
we had to replace the speed sensor in mine and it corrected the problem with the speedometer and the shifting. Good luck
Speedometer flat. This may be affecting transmission.
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
There are many signs of a bad transmission and it is important to know them. Some ways to tell if transmission is not working right, would be rough shifting, leaks, and warning lights on the dashboard blinking.Ê
You need to replace the speed sensor. It sends a signal to the speedometer and also sends a signal to the transmission on when it should shift.
Could be your speed sensor on your transmission
check your speedometer sensor located back left of engine bay on top of the transmission
If the speedometer needle is going crazy and not working properly, it is probably the speedometer mechanism that needs to be replaced. It could also mean the vehicle is having a transmission slippage problem if the needle is bouncing back and forth.
If the spedometer is not working and the traansmision will not shift out of second it means the speed sensor is bad, unpluged or the wiring for it is damaged. The shif6ts are controled by the ECM (computer) and if does not know the speed of the car, it will not shift.
ABS will no longer work (properly).Depending on the car, it might either keep working otherwise, or go into the car equivalent of "safe mode", only allowing low speed driving to get it out of traffic and into service.Could also have a inoperative speedometer, a check engine light, and a not shifting transmission.
