Dorman - OE Solutions Automatic Transmission Speed Sensor P/N:917-620
Dorman 917-647 sensor for the 2011-2018 Ram 1500 and other vehicles is an automatic transmission speed sensor that supplies the speed signal behind speed-dependent vehicle functions.
An erratic or dead speedometer, or shifting that feels off, can mean the sensor is failing. Before you replace the sensor, rule out a damaged wire or a loose connector at the plug. The 2011-2018 Ram 1500 takes one.
This sensor fits the 2011-2018 Ram 2500, the 1999-2013 Jeep Grand Cherokee and many other models. If your vehicle isn't named here, look it up in the "Vehicles it fits" section.
