So I had no reverse lights on my '04 F150 FX4 this morning. Thought it might of had to do with my new led back ups i put on. checked the fuse, good, bulb, good, tow light connectors, brakes good no back ups.
Finally came to the conclusion that it's the "Digital Transmission Range sensor" or "DTR"?? Supposedly that have a tendency of going out? Anyone know how hard it is to put a new one on or how much this part costs?

Thanks!
