2001 4.7L. Truck is running fine. Shifting a little late but fine there no noises. It started with code P0715. Input turbine speed sensor. I replaced the sensor. Light stayed on. After about 100 miles pulled the sensor and it has been ground down to the copper. I compared both the sensors and then noticed that the original sensor was also started to wear in the same spot. I've attached pictures of both inside where the sensor sits and of the ground down sensor. I do not know what is on the other side of the sensor but it also seems to be damaged now. I compared the new and old sensor and they are the same length. I know I'll probably have to take it in to a transmission shop. However if anyone can give me some advice as to what is actually going on I appreciate it.
