Hi, I have a 2000 3.9L Dodge Dakota that seems to be having a malfunctioning vehicle speed sensor. It shifts at too high RPMs. No other symptoms (speedometer, ABS, etc all functioning correctly). How do I replace the VSS? The more detailed the better. Thanks, ADAM
2000 Dakota Vehicle Speed Sensor

If the speedo and ABS are functioning, then the VSS is fine (that's located on top of the rear differential). What may be an issue (and this is a 'maybe', because any number of things could cause erratic shifting) is the transmission's output speed sensor, which is located on the side of the transmission, in the overdrive section (furthest back, or away from the engine). It's a two-wire sensor. You unplug the electrical, unscrew the sensor, make sure the O-ring comes out, screw the new sensor (with new O-ring) back in, tighten, re-plug the electrical, and replace any transmission fluid that leaked out.

The codes from the check engine light say that there is a malfunctioning vehicle speed sensor. Would this problem be include in that message? Thanks for the help?
