Since last rain fall my tranny has been acting odd would skyrocket everyone I would shift and now won't shift at all.

The check engine light came on with the code p0720 and p2106 so I replace the speed sensor located on the driver side on the front of the tranny and still the same issues and codes what am I missing. It's a 2004 f 150 with a 5.4 engine. Could the wire harness be bad in the speed sensor or is there another sensor I am missing. Please advise

 

IF you changed the sensor towards the front, that's turbine speed sensor and the wrong one. change the output shaft speed senor, which is toward the rear and the sensor on the right in this picture.

 

Thanks I changed the second one in the pic now I think I will change the first one.

Does anyone know or have a pic of the sensor
