Output Speed Sensor keeps burning up. What would cause this?

What is your question?

The output speed sensor on my 2004 MINI Cooper (Automatic/CVT) keeps burning up the wires of the sensor. The sensor has about a 6" pigtail connected to the sensor. The sensor is a three wire sensor (one to the engine compartment fuse box and 2 to the engine computer). I have replaced the Engine computer, transmission module, engine wire harness, valve body, and engine fuse box. Have you seen this problem before and know what may cause it? Thank you, Chris
