2006 Ford F250 P0743 and P0744 Codes Returning After Replacing Solenoids, TTF Temp Sensor, and Fluid Flush

Model: F250 Fault Code: P0742 Posted: 2019-12-27 12:35

I have replaced all solenoids related to the P0743 and P0744 codes, along with the transmission temperature sensor, performed a complete fluid flush and filter replacement. Despite these efforts, the codes persist. I cleared the fault codes and reset the camshaft position sensor, but now when I start the truck, there is no power to the gauges. I've checked all wiring harnesses connected to the transmission for breaks. This is a 2006 Ford F25 or 5.4L V8 diesel engine with 300,000 miles and very clean maintenance history. What could be missing in my diagnosis? Any insights on troubleshooting these specific codes would be greatly appreciated.
