How to Service and Repair a Vehicle Speed Sensor on a 5R55E Transmission on Mercury Mountaineer?

You must raise the 5R55E vehicle before starting the Transmission Speed Sensor service. The service of the 5R55E requires disconnecting the output shaft speed (OSS) sensor electrical connector while removing the OSS sensor by uninstalling its OSS sensor screw followed by sensor extraction from the transmission. Ascertain whether the OSS sensor O-ring displays signs of damage before deciding to replace it with a new one. Petroleum jelly should be used to lubricate the new O-ring before putting the OSS sensor back into the transmission. The OSS sensor installation requires securing the sensor by fastening the screw and reconnecting the electrical connector. Finally, lower the vehicle.
