Q: Car was not showing correct speed on speedometer and now the car won't shift into any gear (manual)

asked by on

The check engine light is on. Car was having the speedometer needle jumping around not posting any correct speed reading. And finally the car doesn't move in any gear including reverse.

My car has 247000 miles.
My car has a manual transmission.

This may likely be caused by a faulty transmission speed sensor. The speed sensor reads the rotational speed of the reluctor wheel, located within the transmission. The speed sensor also controls the anti-lock braking system. Driving with a bad speed sensor usually causes the ABS to malfunction and can lead to loss of braking power and/or an accident. When this is not working properly, you may also notice the transmission hesitating to shift gears, erratic tachometer readings, the speedometer not working properly or the odometer not working properly. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
