There is a gear inside the trans below the sensor that be worn out. You need a trans shop to verify and get the correct gear.

Hello,

If you don't have a check engine light on I would say the problem is the stepper motor that runs the speedometer gauge. These motors go out all the time. You can remove the cluster and have it rebuilt or try replanting the stepper yourself you can get it on Amazon.

Please let us know what happens.

Best, Ken
