I have replaced te speed sensor the dealer replaced the speed sensor harness . Fault code keeps coming back . All this started after dealer put in new transmission . Any ideas . 2013 CXU613 Vin# 048577
If this is an MDrive transmission it is quite possible that the tone ring inside the transmission was damaged while the top plate was being installed by the dealer. It is a common mistake (that I have made)
No it is not a M Drive. Has he eaton transmission in it. I was kind of thinking along the same lines that there may be a problem with the tone ring but when I change the sensor I did feel the tone ring.
